Ask Slashdot: Practical Alternatives To Systemd?

First time accepted submitter systemDead (3645325) writes "I looked mostly with disinterest at Debian's decision last February to switch to systemd as the default init system for their future operating system releases. The Debian GNU/Linux distribution is, after all, famous for allowing users greater freedom to choose what system components they want to install. This appeared to be the case with the init system, given the presence of packages such as sysvinit-core, upstart, and even openrc as alternatives to systemd.

Unfortunately, while still theoretically possible, installing an alternative init system means doing without a number of useful, even essential system programs. By design, systemd appears to be a full-blown everything-including-the-kitchen-sink solution to the relatively simple problem of starting up a Unix-like system. Systemd, for example, is a hard-coded dependency for installing Network Manager, probably the most user-friendly way for a desktop Linux system to connect to a wireless or wired network. Just this week, I woke up to find out that systemd had become a dependency for running PolicyKit, the suite of programs responsible for user privileges and permissions in a typical Linux desktop.

I was able to replace Network Manager with connman, a lightweight program originally developed for mobile devices. But with systemd infecting even the PolicyKit framework, I find myself faced with a dilemma. Should I just let systemd take over my entire system, or should I retreat to my old terminal-based computing in the hope that the horde of the systemDead don't take over the Linux kernel itself?

What are your plans for working with or working around systemd? Are there any mainstream GNU/Linux distros that haven't adopted and have no plans of migrating to systemd? Or is migrating to one of the bigger BSD systems the better and more future-proof solution?"

Accept, don't fight, systemd

[Bryan Ischo]

Whether you love, hate, or are ambivalent about systemd, I think you have to accept it at this point. If there are things you don't like about it, trying to use an alternate init mechanism is only going to cause you personal grief that will likely only increase in severity over time as it gets harder and harder to retrofit software packages to use other init systems as systemd further embeds itself into the Linux software world.

If there are things you don't understand about systemd, you should read as much as you can to try to figure it out for yourself, and if you can't, you should write up coherent questions and post them in the appropriate forum for help (what is the appropriate forum? I don't know - someone jump in here and help me out. I personally often have no idea where the best place is to ask questions about things like systemd).

If there are things you don't like about systemd, you should write up coherent bug reports or feature requests, and get them in front of the right people (once gain, someone jump in here and say who these people are and how to get these types of requests out there, I actually don't know). Or better yet, make the improvements to systemd yourself if you are capable of doing so.

Your goal should be to improve both systemd itself and your knowledge of how to use it to the point where it is something you are happy to use, not work around it. By hook and by crook, systemd has become the standard way of doing many things in a typical Linux system and it's time for all of us to just accept that and to make forward progress. It's too late to try to work against systemd; it's time to "embrace and extend".

If systemd is so onerous to you that you can't use Linux anymore, then I guess BSD is a possible solution for you. But who knows, maybe BSD will eventually adopt systemd as well?

Re:Accept, don't fight, systemd

Don't hold your breath that BSD will adopt systemd. Maybe FreeBSD, but they are basically Linux flavoured BSD anyway. But the _serious_ 4.4BSD based systems just don't see the need, and are happy with the few lines of code that makes up a safe init.

Solaris has it's own abomination called SMF. Good luck debugging network problems on Solaris without a GUI unless you're experienced with SMF. I use Solaris only to maintain my open source projects (I value portable code), and I _hate_ dealing with the system. So convoluted.

The system with the most straightforward configuration and init system, IMO, is OpenBSD. It's soooooooo nice. The only major change in nearly 15 years has been the move to an rc.d/ (init.d-style) startup script directory. Contrast that with number of convoluted changes in Linux administration over those past 15 years, and it seems like a miracle.

If SMF and launchd (OS X) are any indicator, I'm definitely going to hate working with systemd.

(NOTE: I haven't used Slackware since the 1990s, so maybe it's remained stable all these years, too. For Linux I tend to only use Debian and Ubuntu.)

Hate to break it to you, but when you install a distribution, you have a lot of software "shoved down your throat." It is what a distribution is, after all, and has been the case since forever. The maintainers decide what functionality is in the base system, what packages are installed in meta packages, what versions, what optional features to compile in. The only way around it is to use a source distribution like gentoo.

Also, Lennart Poettering has noted he doesn't care about support anything !Linux, even if someone else maintains the code.

First technical: with OpenSSH the OpenBSD guys have clearly shown that this is the correct approach. Write correctly for one platform and have a second team write a compatibility layer.

Second attitude: this is the same fucked up anti-user attitude as the Gnome people. If this was a bunch of hobbyists writing their new operating system hypervisor in Haskell for fun then I wouldn't care, however these are a bunch of serious people actually paid by RedHat. What would it cost them to say something like "hey guys, we don't have time but we would love your help with this"

Third reality: recently I messed up my systemd based system. Finding "systemctl -xb" you just realise that there actually is something neat about the system being able to understand it's own logs. Finding out that your system is failing to boot because of one directory permission (/var to the wrong user) and that it doesn't start a shell at all or anything you can debug with is just disappointing.

Sysemd is both better and worse than everything before it at the same time. There are a bunch of brilliant ideas. Someone need to refactor it instead of just complaining about it. Implement the exactly same functionality in a system which has a tiny init process. When you do that you will rove that Lennart is wrong. At the same time you will also prove that some of his ideas are right.

Systemd is not gospel, it is just so good that distributions and especially 3rd party software like gnome, KDE, polkit and more start to depend on that functionality. Write something better that provides these benefits and they move to your solution.

Then *BSD will cease to be a Unix.

If they don't provide the functionality that is provided by systemd, then they will become even more irrelevant than they are now.

Re: Accept, don't fight, systemd

[Rutulian]

Never used SMF, but systemd is quite a bit better than launchd. The configuration files are all plain text. The major difference from a configuration point of view is that instead of writing a script, you just specify executable information, dependencies, sockets, etc, in a config file. That's it. Doesn't seem like such a big deal to me and in many ways seems quite a bit better than sysV.

Re:Accept, don't fight, systemd

[Ereth]

SMF didn't replace init. Init is still there. It will still run legacy rc.d scripts, just like always.

SMF incorporated the existing common rc.d scripts and gave them dependencies, so that, say, Apache doesn't start if networking is down. It also gives you the ability to bring up the entire stack by simply starting something at the top, and it's aware of what beneath it needs to be enabled to work. It also gives you a log of everything starting up, so you can track down the problem (though, granted, often the log is not particularly useful - "restarting too often" doesn't tell you as much as I'd like).

I don't know what problems you are having debugging networking problems in Solaris, but I do it all the time, from the command line. I don't know any serious Solaris admins who use that god-awful SMC gui tool. We all use the command line. And Solaris maintains backwards compatibility, so we still have ifconfig, and snoop and all the same tools you've had since Solaris 2.5 available to you.

SMF is all XML, if you want to read the configuration or make your own, you can.

the systemd init may be brilliant, if it would be isolated. But its mixed up with udev, syslog and even gnome to some extent. This cannot be an good idea, because stuff like init needs to KISS.

Re: Accept, don't fight, systemd

[amorsen]

The configuration system for daemons that systemd has is an enormous leap forward over the old shell scripts. If systemd would stick to be an init system, it would not be such a problem.

When it takes over file system mounting, including hiding most mount points from /etc/fstab and breaking silently if there are perfectly valid mounts in there which it happens not to like, people complain.

When it takes over system logging, previously one of the major advantages of Unix-based systems over Windows, people complain.

And so on and so forth.

Re:Accept, don't fight, systemd

[Bryan Ischo]

OK fine then, don't accept it. Waste your time and money fighting the inevitable, just so that you can be "right", when you could have spent less time and money cooperating on fixing the thing so that you can be "right" *AND* have more time and money in the end, and a better outcome all the way around.

Look, I don't love systemd; I quite dislike it in fact. But it should be pretty clear to any moron that it's already become entrenched and it's not going anywhere. So you can cry and try to take your ball and go play in your own ever shrinking room, or you can try to improve the bed that you are inevitably going to have to sleep in.

My advice was to wake up, wise up, and try to positively affect the ecosystem that you live in, instead of crying and living some kind of pipe dream that you'll be able to use Linux and not have to use systemd.

Maybe the question is why these other packages feel the need to mandate the use of systemd. I haven't done system administration on linux for some time so I don't know, but has it gotten so complex now that it's impossible for packages to remain independent of the system init, or to have an portable interface to the system init?

And is systemd "standard"? There's a lot of linux systems that don't use it, and many non-Linux systems that don't. Forcing one solution is not the Linux way of doing things, and it certainly is not the Unix way of doing things.

Why not change your words slightly so that they say "By hook and by crook, Windows has become the standard way of doing many things in a typical PC system and it's time for all of us to just accept that and make forward progress"?

Finding "systemctl -xb" you just realise that there actually is something neat about the system being able to understand it's own logs. Finding out that your system is failing to boot because of one directory permission (/var to the wrong user) and that it doesn't start a shell at all or anything you can debug with is just disappointing.

I guess you mean "journalctl -xb". Even so, I had an issue with a mount failing (not a critical one), and systemd dropped me into a what it called a root shell. (See #733232 for a similar situation). Of course, then the system was practically fully up, so the shell was fully functional. However, I refuse to believe that systemd can't start a shell to debug. It might not do so by default, but it can. See http://freedesktop.org/wiki/Software/systemd/Debugging/ (and https://fedoraproject.org/wiki/Systemd_early_debug_shell for what I presume is an older guide).

A few years ago I would've called this ludicrous. I've been using FreeBSD for almost 20 years now and the idea of something like systemd (and the horrorshow it's become) making it's way into the base system was laughable. These days, I'm not so sure. Every release seems to take the system one step closer to exactly what you describe, with occasional steps the other direction (such as llvm/clang replacing gcc). I doubt FreeBSD will use systemd any time *soon* but one day, it might. By then bsdinstall will probably have been replaced with something even worse as well, and I will have moved on to some other flavor.

Re:Accept, don't fight, systemd

[Wheely]

One thing that made me thump my head against a wall with SMF was when a system booted but I couldnt ssh into it. sshd was not started because utmp was not "enabled" because mounting the filesystems failed because a single file system didnt mount. Ok, its fixable but sshd ran perfectly if started manually and it delayed getting production systems up by a few minutes. We get journalists knocking at the door if our systems are down.

I hate this stuff, none of my admins remember where the damn log files are because they play with it so rarely. A load of scripts run in sequence can easily be followed, however rusty you are.

Wasn't there an init method prior to SystemV?

Why assume that SystemV init is the once-and-forever solution to UNIX startup? If systemd represents a superior design it will almost certainly supplant SystemV. If not, there will be some painful moments fixing the damage - but I'd rather adapt and grow with risks than stagnate and age in perfect safety. NOTE: most businesses will disagree vehemently with that assessment, and for good reason. Time for we technical types to either ensure that systemd is up to the task, or to reveal its shortcomings quickly to minimize the pain.

Or better yet, make the improvements to systemd yourself if you are capable of doing so."

This advice does not fit the situation at all. Bug reports and feature requests? You do not fix a fundamentally mis-specified and mis-designed program with bug patches and requests for even more misfeatures!

"Your goal should be to improve both systemd itself"

This makes no sense whatsoever. I dont want to 'improve' it I dont want it period. Init works great. It's not broken, dont fix it.

"By hook and by crook, systemd has become the standard way"

Negative. Init is the standard way. What's happened is that the number and visibility of the deviationists has increased. Popularity along is not sufficient to change a standard.

"If systemd is so onerous to you that you can't use Linux anymore"

Usually it's intentional equivocation masked as an attempt to sound intelligent or continue the argument when they no longer have a real point.

Re: Accept, don't fight, systemd

When it takes over file system mounting, including hiding most mount points

I can see how this is annoying, especially when you don't know what is going on, but mounting filesystems is an integral part of the startup process and therefore should be managed (in part) by systemd. It was manged using the old sysV scripts too btw, so it is consistent as far as init systems go. The difference with systemd is it actually knows what a filesystem is and that it is different from a service, so it can manage and monitor them accordingly. What this means is that filesystems associated with booting (root, swap, dev, ...) are now systemd entries instead of /etc/fstab entries. Once you realize this, it is not that hard to manage. And /etc/fstab does still work, of course, for filesystems you want to manage yourself. There are reasons you might want to create systemd entries for those too, though. Automounting, for example, is handled much better with systemd than the old autofs route that we had to use before.

and breaking silently if there are perfectly valid mounts in there which it happens not to like

That is either a bug, or possibly a conflict. Again, I can see how it is annoying, but if you have an /etc/fstab entry that wants to steamroll a systemd entry, it is understandable that systemd will try to stop that from happening. The correct fix in that case would be to edit the systemd entry to match the changes you are trying to make with the /etc/fstab entry.

When it takes over system logging

So, systemd doesn't just start/stop services, it also monitors them and can be configured to take certain actions depending on what happens to a particular process. So, needless to say, logging is kind of inherent to the whole thing. Correct me if I'm wrong, but I don't think it "taking over logging" is your real objection, but rather the way in which it does its logging. Instead of splitting things into separate text files that are managed by their respective daemons, systemd collects all this information and stores it in a standardized, indexed way within its own file. This is a design decision, and with all design decisions there are tradeoffs. In this case you are sacrificing the ability to just cat/grep individual text files for the ability to filter and have other processes able to monitor the log files, as well as some benefits for auditing and security. I definitely prefer text files because I don't manage complex scenarios, but I can also see how journald is critical for certain enterprise infrastructure. If you don't like journald, you can install syslog-ng. You just have to make sure it doesn't trample on journald (ie: it has to listen on the journald socket instead of /dev/log). I believe CentOS 6 is configured this way (journald+syslog-ng), so it is not that unusual or hard to do.

Re: Accept, don't fight, systemd

[Anonymous Coward]

Plain text alone doesn't make for a defensible configuration system. .ini files are stupid. yacc was invented 30+ years ago so people with half a brain could easily support configuration files with a proper and useful syntax. Syntax should help to hide complexity. .ini files have almost no syntax, and therefore pushes all the burden on the human. That's idiotic.

For heaven's sake, it's 2014; we have beautiful new parsing concepts like PEGs, which blow regular expressions out of the water. It's not hard to parse complex syntax anymore. Why the heck would anybody use .ini syntax for anything non-trivial? (Spoiler: because they're not paying enough attention to the details that actually matter.)

Re:Accept, don't fight, systemd

[Darinbob]

The basic legacy init has been around for decades because it works. It's small, it's simple, and it fits the design concepts of the early Unix systems. If you didn't like the init system then you changed the initial rc script. The various replacements for it over the years have seemed to be just minor tweaks (the directory structure of rc files) or else more major rewrites that never really catch on.

Systemd criticisms seems to be mostly about two things: re-using pid 1 to do more than it was initially intended to do, and too much functionality is included in one daemon (ie it has "mission creep"). The fact that unrelated apps are requiring systemd should be blamed on the apps I think, I don't follow this enough to know if there's any sort of collusion.

And "Oracle" in this context is really a lot of Sun engineers that were inherited by Oracle, so I would give them a lot more credence than I would to legacy Oracle people.

The problem with systemd is that it does waaaaaay too many things, by design. What people want is less features in systemd, not more.

Systemd is a very stupid short-sighted solution to a problem people didn't have, and if not reversed, will be in a few years a huge pain to linux, due to its scope creep and everything-including-thr-kitchen-sink approach to daemons & hardware management...

There are plenty of people who would rather have nothing to do with systemd. The correct response is "to each his own", not "Deploty the dependency hell!".

So, systemd doesn't just start/stop services, it also monitors them and can be configured to take certain actions depending on what happens to a particular process.

I see no reason that should need to touch system logging at all other than adding a log entry if it has to take action.

Specious argument. Nobody said you *have* to accept systemd. I said you *should* accept systemd, and I gave reasons why you should.

Whether you love, hate, or are ambivalent about systemd, I think you have to accept it at this point.

Re:Accept, don't fight, systemd

Yes, there was. For a long time, they existed in parallel. Nobody minded because neither tried to make everything under the sun depend on it rather than the other.

In fact, there's no technical reason systemd couldn't peacefully co-exist.

Re: Accept, don't fight, systemd

I'm not sure if you are arguing it is better for the computer or better for the human reading it. I dunno, I prefer human-readable plain text files over an easily parsable "complex syntax", especially for something as basic as the init system. That's why I (mostly) hate xml as a configuration file format (*cough* launchd *cough cough*). It is good for making guis, but terrible if you ever need to edit the file by hand at a terminal.

Re: Accept, don't fight, systemd

[Rutulian]

Maybe, but I don't know when "back when" was. A distribution has to make some choices about how to package things and that necessarily removes choice from the end user. Most basic example of this, the package manager. You can't really choose which one you want and which format. The distribution chooses the package manager, you choose the distribution. Or better yet, initmodutils, replacing insmod with modprobe. It's funny how users seem to fine with that, but when the distribution makes a decision they don't like, then it is being "shoved down your throat."

Linux and open source software in general has always been about survival of the fittest software, not by software being enforced by a company and by a bunch of people who haven't the faintest idea what they are doing. systemd is the total antithesis of the Unix philosophy - do one thing, do it well and have a bunch of focused interconnected system.

The people behind systemd are the same people who Linus Torvalds exposed as morons who kept breaking udev:

The difference is in "I think you have to" versus "You have to".

Yes, there is a difference. Saying "you have to" is a command, and it does take away freedom when it is spoken by someone with authority to do so.

Saying "I think you have to" is the same as saying "you should". It's not a command, it's a suggestion.

Do you see the difference now?

Re:Accept, don't fight, systemd

[Bryan Ischo]

Your statements are more prescient then I think you realize.

It IS kind of like the Borg; there is kind of like a "hive mind" in open source; whatever the most people think should happen, is what will happen. There is no central authority to dictate that anything other than what the majority wants should happen.

In this case, it's pretty clear that, since all the major distros have accepted systemd, that it's been accepted by the majority of users and become the de facto standard. There seems to be alot of momentum behind it.

I could of course be wrong; maybe it just looks that way, and maybe there is enough of a seething hatred underneath the covers for systemd that it will be ousted soon. But in the meantime, what are you going to do? Just hope, pray, and wait for that to happen? Why not try to improve the thing instead of complaining about it hoping it will go away?

An alternative to my suggestion that people accept systemd and learn to use it, and work to improve it to make it better, is the suggestion that you "take to the streets" and actively fight against systemd rather than accepting it.

You can suggest that to people if you want to; it's just that I don't think it will work and I think those people will waste their time and energy. And I won't suggest to people that they should waste their time and energy on something, especially something that has no moral or ethical implications and is just freaking OPEN SOURCE SOFTWARE that we can all change for the better if we want to.

No, we do not. The systemd bloatware has infected a huge number of GNU/Linux distributions at this point and it has become integrated with all sorts of things on those distributions. It has become as good as impossible to avoid on the distributions that has adopted it. Luckily you are WRONG, you see resistance is NOT futile. The obvious solution is to NOT use the distributions that have submitted to the systemd world order. Gentoo and Slackware are good alternatives to Fedora, Arch and now sadly even Debian. US Department of Defence subsidiary RedHat can force their NSA-backdoored systemd on some but they can't and won't fool us all.

Re: Accept, don't fight, systemd

[amorsen]

What this means is that filesystems associated with booting (root, swap, dev, ...) are now systemd entries instead of /etc/fstab entries.

What would have been lost by adding them to /etc/fstab? That way you would be able to tell systemd not to mount them, if need be, or to mount them elsewhere.

standardized, indexed way within its own file.

Said standard being the systemd source code of the day. No external tools can handle the format. journalctl performance is a complete joke, and that is in comparison to full-text grep of the text files -- quite an accomplishment actually.

"Note that the actual implementation in the systemd codebase is the only ultimately authoritative description of the format, so if this document and the code disagree, the code is right."

Re:Accept, don't fight, systemd

[t_hunger]

The problem is: A *tiny* init process won't be able to offer the *exactly same* functionality. The functionality has to come from somewhere, it does not fall from the sky: Some code needs to implement it.

If you want to keep PID 1 tiny then you can implement the actual functionality in separate processes. You now have two or more process and now you need code in the tiny init process that makes sure the controlling processes are getting started (and restarted). Remember: Those daemons provide the actual functionality, so PID1 can not depend on that to start those daemons in the first place.

You need code that facilitates a communication channel between the processes. You need code to lock out processes that are not meant to talk to your tiny init process. You need a protocol that the init process speaks and that allows it to be remote-controlled. All of sudden that tiny process is no longer tiny and your architecture is much more complex than it would be otherwise.

That complexity requires you to add more code to mitigate communication failures, to synchronize data structures between all the different processes that need access to them, you need to be careful not to introduce race conditions between those processes. In the end you end up with a pretty big init process and a bunch of big and nearly equally critical daemons surrounding it. I do understand where the systemd guys come from: Keep the architecture simple, and put absolute minimum amount of code into PID1 to provide the functionality they want. That makes the overall system less complex and easier to reason about, which is good for security and robustness.

Read the code, it is actually pretty ok.

Re: Accept, don't fight, systemd

[Rutulian]

Or it could just honor fstab since that has always been the correct way to specify mounting a filesystem.

Not really. If systemd is monitoring the mounts, which it does because executing mount -a at some arbitrary point during the boot process is not the best way to mount the required filesystems during boot, it makes sense for it to give priority to it's own config files. Anyway, I don't know the exact nature of the problem, but I suspect it is because systemd mounts filesystems before /etc/fstab is parsed. If you try to mount an already mounted filesystem, it will just get ignored. This is the default behavior of the mount command and has nothing to do with systemd.

I see no reason that should need to touch system logging at all other than adding a log entry if it has to take action.

Agreed. It doesn't need to, but the two activities are logically connected. Technically, journald is a separate service from systemd that is designed to work well with systemd, and it collects a lot more information than your basic syslogger. It is not required, though, and you can continue to use syslog if prefer it.

Re: Accept, don't fight, systemd

[segedunum]

That is either a bug, or possibly a conflict. Again, I can see how it is annoying, but if you have an /etc/fstab entry that wants to steamroll a systemd entry, it is understandable that systemd will try to stop that from happening. The correct fix in that case would be to edit the systemd entry to match the changes you are trying to make with the /etc/fstab entry.

You're missing the point here. I'm not troubleshooting that needless complexity on a remote server, and the problem here is needless complexity.

but I can also see how journald is critical for certain enterprise infrastructure.

That is a meaningless statement.

If you don't like journald, you can install syslog-ng. You just have to make sure it doesn't trample on journald...

Great.

Apache doesn't start if networking is down.

Re:Accept, don't fight, systemd

[s.petry]

Like systemd, SMF can do things similar to INIT, still reads INIT directories, and has a set purpose. One of the reasons I didn't mind SMF was that it's hackable. You have to know where to hack things, but outside of locations for scripts it's not that different.

Remember why Sun implemented SMF? The primary driver was that init runs once, and something was needed to actually manage and monitor daemons. I have used various monitoring tools and cron hacks to do similar things over the years, but SMF made this much easier to manage. SMF took away the need for external monitoring and maintenance tasks. (Obviously not completely because things still break, but normal errors or hang ups were easy to resolve.)

Since SMF could still run legacy scripts just like the old init including reading and processing inittab, I honestly fail to see how anyone can claim it's an abomination from a position of knowledge. I have seen plenty of ignorant people make such a claim, nothing new there.

Since systemd is still supporting init scripts and methods I'm not sure why this has become such big deal either. Now if there is no legacy mode, there is a different issue. If you don't want systemd to start your apache, write an init that does and disable the systemd start for the OS released boot script.

Personally, I'm of the opinion that old init is just fine. I worked fine with init for decades, and don't necessarily need a change to be happy. At the same time, I am aware of "why" people want better features than init provided. As long as legacy is supported why would I complain? I can still run boot scripts I wrote in the 80s without any modifications.

The OSS sound system disappeared in favour of ALSA, XFree86 vs Xorg, the LVM changes come to mind, etc.

Many many things in open source are up for simply flipping because there's a better option. As soon as a better option to systemd is available, I sure hope it gets jumped on because I'm quite sick of systemd already myself.

Aside from some GNU software (GNOME in particular), what do you think is going to change that much? And BSD doesn't use most of the GNU software anyway.

Re: Accept, don't fight, systemd

[Anonymous Coward]

Again, I can see how it is annoying, but if you have an /etc/fstab entry that wants to steamroll a systemd entry, it is understandable that systemd will try to stop that from happening.

Or it could just honor fstab since that has always been the correct way to specify mounting a filesystem.

Why exactly would systemd not use fstab for it's "own" mount table? Sounds totally stupid to change the location of a file that has been the location for filesystem mounts for decades, and looked at by potentially 100's of other programs that might then have to be changed.

However, that does seem to be the "systemd" way - exactly what Linus ripped that one developer for not long ago, "force everyone else to change their code in potentially 100's of places because I'm too lazy to maintain consistency with how it should work nicely with everyone else". Exactly why I plan on moving either to BSD or just about *any* variant of Linux that doesn't use it, and if they all do then I'll be going entirely to BSD.

So, systemd doesn't just start/stop services, it also monitors them and can be configured to take certain actions depending on what happens to a particular process.

I see no reason that should need to touch system logging at all other than adding a log entry if it has to take action.

I see no reason to monitor logs at all since it should be the parent that launched the processes and thus should know if they die, segfault, etc (if they have the signals enabled). Besides, something that is continually scraping the logs looking for potential failures is commonly known as a "monitoring system", which should be the realm of a package made for monitoring (everything from OpenView commercially to Nagios as open source) and *not* a function of a sysinit process.

Re: Accept, don't fight, systemd

[sjames]

If and when failures of mounted filesystems is handled gracefully, monitoring might matter. If this was just a matter of something in fstab already mounted, it wouldn't cause a problem. It shouldn't even be a problem if it's already mounted elsewhere (these days, you can mount a single filesystem more than one place in the tree).

If it's breaking, it's because systemd is going out of it's way to break something. That is not the sort of behavior I want to see in my init system. One of the virtues of Linux is that if you are root, it will do what you say if it is at all possible. It will try even if it isn't possible.

Re: Accept, don't fight, systemd

[sjames]

As for the restarting thing, OI had that working cross platform back in the '90s. Restarter was a simple daemon that would run another process and watch it. If the process failed, it would re-run it and log the event. It integrated cleanly with Solaris, Linux, Irix, *NSD, and even Unicos. No need to trash the whole OS just for that capability.

It could easily be integrated with dbus and listen for events if that was actually desirable. No dependency hell, no turmoil, no "my way or the highway" mentality. Use it or don't.

If anything, I'd expect it to be the reverse - large pieces of software that introduce systemd dependencies will lose users (especially when there are other good reasons to migrate away, as is the case with e.g. GNOME), and smaller pieces will simply be replaced.

Or because someone is lying to themselves, or trolling, or stroking their own ego independent of trying to sound intelligent.

Often they boil down to syntactic or semantic arguments, belaboring point after point until those with solid points are swarmed by nits.

I'm not sure what it has to do with syntax, maybe you don't know what that word means, and why syntactic arguments would be different than the much too common semantic arguments.

I hate this stuff, none of my admins remember where the damn log files are because they play with it so rarely.

If you use illumos or Solaris 11.2, svcs -L gives you the path to the service log. I use "grep foo `svcs -L bar`" all the time.

I use SMF a lot, and I've rarely had trouble with it. svcs -vx shows you which services are down (as well as the log path, hello), and you take a look at the log to see what your application is complaining about. I have consistently found it easier to use than init scripts, despite me usually having a very conservative OS bent.

The only thing I don't like about SMF is the XML.

Re:Accept, don't fight, systemd

[Marsell]

Solaris was abandoned for reasons completely unrelated to SMF and its various technologies. If anything, Solaris 10 was a decade ahead of its time (DTrace, ZFS, zones, crossbow).

It's just that by the time Solaris was opened, the mindshare and momentum was vastly with Linux. It never stood a chance, completely unrelated to its technical merits, and Oracle closing it again just sealed the deal.

Having said that, illumos (an OSS version of Solaris that forked a few years back) is awesome and actively developed by several companies making money with its technologies.

Re: Accept, don't fight, systemd

[Rutulian]

Like I say, I don't know the details of the original poster's situation. All he said is "breaking silently if there are perfectly valid mounts in there which it happens not to like." What does that mean? My best guess is systemd is mounting something initially first, and then the subsequent mount -a that reads /etc/fstab doesn't do what you expect because mount will not change mount options without special instructions. It is not breaking anything. It is the normal expected behavior of the mount command that has nothing to do with systemd. If you want to override something that systemd is doing, you will naturally have to do it the systemd way. I don't see why that should be surprising or unusual to anybody.

Re: Accept, don't fight, systemd

[Rutulian]

What would have been lost by adding them to /etc/fstab?

Well, then it wouldn't be managing the mounts. It would be just executing mount -a, just like a sysV script. This works fine in some ways, but breaks in other ways. For example, a container that uses an iscsi target as its backing store. There is a complex set of dependencies that involves mounting local filesystems, starting network services, connecting iscsi devices, mounting network filesystems, starting the container. Another example is the udev system, which certain services interact with in different ways. There are a bazillion hacks to deal with these issues with sysV that aren't pretty. Systemd solves all of them.

That way you would be able to tell systemd not to mount them, if need be, or to mount them elsewhere.

You can still do that, you just have to do it the systemd way. I know its frustrating to have to learn a new way, but it is not as bad as you think.

Re:Accept, don't fight, systemd

[Marsell]

It was called Slowlaris in large part because of STREAMS support, which was mandatory in SUS v1 and v2. I find it a bit sad that Solaris historically was ragged upon because it basically tried to follow de jure standards to a T, and backwards-compatibility was a high priority.

But that's a different discussion. Nowadays both Linux and Solaris derivatives have similar computational overheads: sometimes Linux comes out ahead, and sometimes Solaris. I think system administration is completely in favour of Solaris, but we obviously have differing opinions on this.

Re: Accept, don't fight, systemd

[sjames]

Do one thing well. Build more complex actions by putting smaller parts together. Swiss army knife system utilities need not apply. That is the Unix way.

Mount -a is the perfect way to mount filesystems needed to init the machine. The rest can be mounted by a daemon as they become available. My / filesystem resides on an HDD that is bolted in to the system, if it's not there, there is nothing to boot, so why does it need to be 'monitored'?

Re:Accept, don't fight, systemd

[Anonymous Coward]

if your PID 1 crashes, your kernel panics, which is *much* more likely to happen with a big complex init.

if your init is just a small boot process that starts the process with actual functionality (or a fallback shell if that one doesn't start), there is no fucking need for it to listen or speak any protocol or be remote-controlled. It can stay tiny alright. All that communication can take place between the sub-process(es) you spawned exactly for that.

That said, the actual problem most people seem to have with systemd, and I'm one of them, is not the PID 1 thing. It's the "make everything and more depend on it" approach. If the previous inits had been developped that way, there is no way we could replace them today with systemd. In a few years from now, we will have a big heartbleed-like mess with systemd and there will be no fucking way to get rid of it unless going back to what will then be an old linux distribution from 2014 (or even earlier, depending on your pick).

Not to talk about the "forced down our throat" thing and the way developpers interact with users. The exact same way GNOME 3 developpers have been: poorly and obnoxiously.

Re:Accept, don't fight, systemd

I don't think you're right about this. One of the nice things about OSS is that you don't have to go with the majority; even a small minority can maintain a usable fork. Slackware has used an unpopular init system for years: it uses BSD init instead of SYSVINIT. I see no reason it shouldn't be able to keep doing that if it wants to, and I don't think Volkerding is enthusiastic about systemd, to say the least. udev doesn't currently depend on systemd, and anyway someone else in this thread said Gentoo already forked it.

By the way, did you know you can run a Linux system, today, without udev? You just create the device files in /dev like you did back in the 90s, and it'll work. That's not to say this is a good idea. But it will work.

I'll tell you when: when GNOME developpers took the path of making it all but impossible to have GNOME properly working with other init systems. And that's just the "I've had enough" point in time, not the one and only example.

Some decision taken over the past years in various linux distributions have been taken not out of technical merit or discussion, but out of personal interests, or for political reasons. Sometimes it comes discreetly through some clever marketing that everyone swallows and when you notice it, it's already too late (systemd), sometimes through hostile takeovers (yes, Debian, I'm looking at you *cough* libav *cough*) where there is nothing you can do as a user because a few guys in power decide what is good for you.

Linux used to be about choice, but the list of these non-technically-based decisions that reduce our options is getting longer and longer recently.

Whatever will happen, don't tell me that the many voices around objecting to systemd have been listened to or their objections to core-design problems addressed.

systemd may very well be the best init software ever written, but then there is the manner. The way it's currently spreading its arms out of its role as an init system in a non UNIX way for political reasons, acting like a kernel above the kernel, is what most people are complaining about. Just read this whole thread, yes there are trolls, but there are sensible people making reasonnable arguments. And what is the answer they're given: "you're holding it wrong".

Re:Accept, don't fight, systemd

Most packages do not depend on systemd being PID1, they depend on other things that found a home in the systemd repository. One big thing is of course udev for things that are close to the hardware. The other big thing is user session management. Basically systemd can replace all the custom start-up-the-desktop-environment code that all the desktops implement to make sure all their services get started and keep running. Then there is logind which manages who is logged in where and who has access to which keyboard/graphics card/mouse/etc. That is pretty essential for any modern desktop environment, too.

Note that all these interesting things are interfaces that can be implemented for other init systems as well. Unfortunately nobody stepped forward to do so yet. The implementations found in systemd are tied to systemd being PID1 (more or less badly), since they e.g. use the systemd interfaces to manipulate cgroups.

SMF is all XML, if you want to read the configuration or make your own, you can.

That's a huge problem, though: XML is a markup language, not a configuration language. Although it can be used to represent any data, it is not ideal for representing many kinds of data (in much the same sense that being Turing-complete is hardly sufficient to be a decent programming language).

YAML, s-expressions, traditional Unix line-oriented config filesâ"heck, even Windows-style .ini files are more useful than XML in the common case.

Some people, when they have a data representation problem, think, 'I know, I'll use XML'; now they have two problems.

Re:Accept, don't fight, systemd

[IllusionalForce]

While I do agree that the post was essentially decently-disguised flamebait, there's one point he really does make: "Whether you love, hate, or are ambivalent about systemd, I think you have to accept it at this point."

I see nobody working on an alternative init system. openlaunchd is both dead and limited to FreeBSD, upstart is likely to die with the march of systemd (Which, as you'll need to understand, is not an init system anymore, but literally a system daemon. It owns, controls and plays with your machine at its own volition and there's nothing you can do to stop it.), OpenRC isn't taken seriously because the gentoo folks propose it and now that both Debian and Red Hat, the two major players on the market, have both decided to play along with the systemd game (one of them was more or less forced into it, but no matter), systemd is omnipresent and impossible to stop.

We would've needed to have a concrete, working answer that made systemd pale in performance, code quality AND documentation back in 2012. If Apple had released launchd as open source back when Ubuntu started writing upstart, things might have ended differently. If upstart wasn't pushed too early, things might have ended differently. However, at this point of time, the UNIX way on Linux is dead. Irrecoverably. I wish I didn't have to paint such a black picture, but it's too tightly-coupled with the rest of the Linux ecosystem to ever remove it again.

I'll tell you when: when GNOME developpers took the path of making it all but impossible to have GNOME properly working with other init systems. And that's just the "I've had enough" point in time, not the one and only example.

So the GNOME project making a technical decision that makes their live easier is forcing something down your throat. You are being a bit egocentric, aren't you?

Some decision taken over the past years in various linux distributions have been taken not out of technical merit or discussion, but out of personal interests, or for political reasons.

Do you have prove for any of those claims? Where are the army of developers that do something about the decisions and flock to projects that are not falling for the propaganda? Or are you the only one that understands what is being played here?

Linux used to be about choice, but the list of these non-technically-based decisions that reduce our options is getting longer and longer recently.

This statement does not become true by repeating it.

FLOSS always had a strong "who does the work is right" approach. What the users say has always been secondary.

Whatever will happen, don't tell me that the many voices around objecting to systemd have been listened to or their objections to core-design problems addressed.

There are loud voices speaking out against systemd. Do not mistake that for many voices. In Debian the systemd oponents failed to find five people required to call for a vote to overturn the decision made by the technical committee! And that after all the fuss taht was raised during the discussion process.

systemd may very well be the best init software ever written, but then there is the manner. The way it's currently spreading its arms out of its role as an init system in a non UNIX way for political reasons, acting like a kernel above the kernel, is what most people are complaining about.

Why bother to write something that is as good as what was there before? Systemd tries to do more than init ever did, right. But much of that actually makes sense if you take the time to read up and think about it.

Just read this whole thread, yes there are trolls, but there are sensible people making reasonnable arguments. And what is the answer they're given: "you're holding it wrong".

I have seen very few reasonable argument levered against systemd in this thread. But then what can you expect from a thread that has an april fools joke listed as a fact?

I mostly see misinformed or uninformed posts. What can you tell people that form a strong opinion on something without bothering to learn about it first? "You're holding it wrong" is actually a rather polite way to put it IMHO:-)

Which _serious_ 4.4BSD systems are those? Net? Open? Certainly not Darwin or Mac OS X, which have had launchd for several versions now.

Meanwhile,

https://github.com/rtyler/open...

is a liklier avenue for BSDs than systemd, if there's ever a move away from the scattering of idiosyncratically formatted files configuration files and shell scripts polluting /etc.

Alternatively, while various post-Open-Solaris distributions downstream from Illumos have adopted lots of Net- and Free- BSDisms (notably pkg and port) there is no reason why more things might go the other way along with ZFS and dtrace. For instance, the Service Management Facility is pretty reasonable once you get used to it and learn to avoid abusing it by simply wrapping up old-style shell scripts that in turn rely upon idiosyncratically formatted config files.

Dynamic network configuration is also an area where *BSD should consider importing things that work from elsewhere. Mac OS X does things pretty reasonably for *clients*, for instance.

You can, actually.

You choose a package manager, then you choose one of the distroes that use that package manager. As for the rest, there are still distroes that offer Freedom of Choice.

I run Slackware. While Slackware does come with a kernel, I was not forced to install it. I never installed it. Yes, that's right, I did not install the Slackware Linux kernel. You see, I was here when the kernel was something that lived in /usr/src/linux, and that's how I still do it. My kernel is installed with "make install", not with "pkgtool".

Slackware comes with KDE. I didn't get KDE showed down my throat, as a matter of fact, the KDE packages were never transferred from the Slackware FTP server to my computer.

And of course, for perfect Freedom of Choice, there's Gentoo.

If I wanted a distro to make choices for me, I would pick the one named "Windows 8".

Re:Accept, don't fight, systemd

[Anonymous Coward]

"why" includes:

Parallel startup of services constrained by dependencies; such fun when one ancillary service or filesystem takes a long time to start up or mount, delaying the startup of more popular services that don't depend on them.

Delegated permissions; "hey, I need to adjust a configuration parameter for service X, I've opened ticket #xxxx as sev. A"

Separate logs; "hey, I can't read /var/log/foo; or, I can't find the debug log for X; or, can you turn [on|off] verbose debugging for X?"

Restarting or otherwise managing services when required, with dependency and delegation; beats adding endless conditions on kill for sudo -u {someserviceowner}, or remembering exactly what signal loads a new config or clears a cache, or remembering what else needs to be restarted when you have to restart a lower-layer service, or "hey can you stop restarting service Z, or maybe not have service Z run at all during maintenance window X? obtw i need to adjust inetd.conf, maybe some xinetd stuff, an init script or two, and a crontab to make the downtime work properly".

Ah, and "complex-multidaemon-service Q is down / never came up! help!!" vs "svcs -xv", which while far from perfect (in part because people can be very minimalist about shoehorning subsystems into SMF) is a lot better than old init.

Annnnd on that last front, any sort of packaging system that tries to outsmart you in editing init scripts and individual configuration files when you do the moral equivalent of "pkg install X" or *worse* "pkg upgrade X" is always tonnes of fun. That's the true breakage of the startup-script + various /etc/*.conf files system we all grew up with.

However, neither SMF nor any of its competitors like launchd or systemd has yet solved my personal favourite hate, namely "cannot mount X/Y/Z, directory not empty" arrrrrrrrgh. (In fact launchd *worsens* that if home directories go away sufficiently early in shutdown, as launchd itself will create files in users' ~/Library/ as may applications and other software being signalled late; this also is a bear with ~/Library/Saved Application State, which really ought to be one of the last things to go away during an orderly shutdown, but only is if everyone's $HOME is on the startup volume). (To be fair, SMF can be made to get this right, and mostly does by default. The "svcadm milestone foo" system is awesomesauce compared to init run levels.)

Re:Accept, don't fight, systemd

[Anonymous Coward]

I've used SMF, and while it's hobbled with corporate XML crappo it is actually very nice to be around, and does things that traditional init systems simply can't do:

  - watch things it starts to see if they exit, and either restart them or simply notice if they do
  - when you tell it to stop something it started, it does so for absolute certain. It doesn't use pid files but rather something like containers
  - understand dependencies among what it starts so that it can
      - start things in parallel
      - restart things that need to be restarted if their dependency is restarted

The main reason I don't want anything to do with systemd is that the developer is an arrogant jerk who doesn't listen, and I'd prefer to be without the capability if getting the capability means being around him.

The second reason is that I'm concerned about security. This desktop software has historically been sloppy, and I think it needs to be more containerized, not less. SMF did not listen on dbus nor do other hydra-like things, and there was no intimate connection between nwam (Solaris's NetworkManager) and SMF. In fact SMF increased containerization because it made setting ulimits and solaris9 "fairshare scheduler"-style limits on the services it started easier to do.

But mostly it's just not worth dealing with jerks to solve simple problems. I think if you excise systemd from your system you will accidentally excise a lot of other jerks as well. NetworkManager is pretty bad. Perhaps a jerk-magnet is what we need to get our Unix back.

In Debian the systemd oponents failed to find five people required to call for a vote to overturn the decision made by the technical committee!

And in Arch Linux, nobody was found who was willing to maintain the sysvinit-scripts package. That is, aftger everyone who voluntered was banned from the forum.

I maintained my own copy for a few months (as I know several others did), then migrated to Slackware. Was the Debian vote restricted to people with a certain level of access, or could any user count against those five? Or did those who disagreed simply see the writing on the wall, and jump ship as soon as the decision was announced? Poettering fans are not exactly known to feel positive about freedom of choice.

That I was using Arch Linux, which at the time had a lot more choice between the standard packages (thus less need to install something from source), and was forced to switch to Slackware, when Arch Linux decided to showe systemd down everybodys throats. Before that, Arch Linux had like three or four init systems to choose from (sysvinit, systemd, runit, possibly openrc), in the spirit of freedom of choice.

Systemd represents the Microsoft way of doing things. Or the Windows 8 way, to be specific (earlier versions had a choice between old and new layout when something changed). If I wanted that, I wouldn't be running Linux in the first place.

Re:Accept, don't fight, systemd

"I see nobody working on an alternative init system. "

There are better init systems in use and supported. Slack init has been it's own thing for a very long time, a bit of a cross between BSD and SysV that follows the slackware philosophy. Simple, robust, and easy to work with.

Gentoo still uses their own fork of init with OpenRC. OpenRC, in a nutshell, provides the features of Systemd or Upstart without breaking compatibility.

Systemd (and upstart, since you mentioned it) is not something primarily created to solve a technical problem. They exist primarily for political reasons. They are Red Hat and Canonical's attempts to rip out the guts of *nix and replace it with vendor-specific infrastructure that they can control and direct.

OpenRC isn't taken seriously because the gentoo folks propose it and now that both Debian and Red Hat, the two major players on the market, have both decided to play along with the systemd game (one of them was more or less forced into it, but no matter), systemd is omnipresent and impossible to stop.

"Because gentoo" makes no sense. Regardless, 'omnipresent and impossible to stop' is bullshit. What is unfortunately true is that Red Hat, Ubuntu, and now Debian will be outside the pale of *nix systems. One large *nix* ecosystem has been effectively forked into three systems. Red hat will own one, Canonical will own one, and the remaining *nix systems, including Linux, Gentoo, and *BSD will remain our own ecosystem that no one can own. It's sad that Debian is officially going the other way but hey, best of luck to them in their new role as Red Hat sattellites.

This is one of the dumbest responses I have seen to a tech problem. The very thought of bending over and taking it from "the man" is the very foundation of Linux and open software. Don't tell me this is the slow creep to a Apple like ecosystem? I think that only small distros should be in the business of releasing distros that are not fully modular. If someone doesn't like systemd for whatever reason please suggest an alternative or leave the blog for someone to do so. The idea of any code/software that is so deeply embedded is revolting to someone like me who depends on skilled and knowledgeable geeks to keep Linux completely modular. Should a serious vulnerability emerge with systemd what alternatives exist? This bend over and take it attitude must not be accepted.
When systems become too entrenched the level of difficulty required to remove those systems increase exponentially. The current situation with Xorg should serve as a warning for any further dependence on any one solution, with all the muscle and will behind Ubuntu they can not truly be described as been weaned from Xorg. Don't let systemd become another of those monolithic structures within Linux, at leaset not one that can't be replaced either by compilation or by a simple package install.

Re: Accept, don't fight, systemd

Well, then it wouldn't be managing the mounts. It would be just executing mount -a, just like a sysV script.
Citation Needed. Systemd would in no way be beholden to utilizing 'mount -a' as the manner in which to parse and execute the fstab file.

Systemd solves all of them.
I fear that many of the issues solved by systemd have done so by ignoring standard practice for defining some very basic aspects of the UNIX-like systems. If systemd were being engineered in a manner appropriate for UNIX-like systems, it could very easily parse these files and act on the data within them in a more intelligent manner than the standard methods. It should be able to identify an iscsi mount in fstab and delay the mounting of it until it has properly bootstrapped the network services. The fact that it obfuscates these things is very much a design flaw.

Re: Accept, don't fight, systemd

[Rutulian]

It should be able to identify an iscsi mount in fstab

How would it do that? Have you ever used iscsi? How about multipathing? It is not as simple as you seem to think it is. Autofs is another hack to make mount + /etc/fstab do something that should be pretty simple, but never works properly. Systemd makes network automounting very clean and easy.

If systemd were being engineered in a manner appropriate for UNIX-like systems

The only thing about /etc/fstab that makes it "proper" is that it has always been there as a configuration file for the mount command! That is all. There is nothing more unix-y about it than having a different configuration file in a different place to do the same basic thing.

The fact that it obfuscates these things is very much a design flaw.

Systemd doesn't obfuscate anything. Everything is very clearly documented, logical, and modular.

Actually, you are arbitrarily declaring it "needless complexity," when what you mean is "this is new and I don't understand it, so I hate it." The reality is it is quite a bit simpler in a number of ways. Whether or not it is on a remote server is irrelevant.

No, it is needless complexity and it is NOT simpler in a lot of ways - not by a long stretch. systemd incorporates a lot of functions that have long been separate and focused. Troubleshooting this monolithic system, and even reading its logs, is a quantum leap harder to do so do not presume to tell me what the 'reality' is in the manner that its maintainers tend to do. I administrate servers where I require a working init system, that's the reality.

Why? That is a meaningless rebuttal.

Because it's meaningless? You've put the word 'enterprise' in there and expect it to mean something. Sorry, but it doesn't. Logs that I can read at a low level are critical for an 'enterprise' infrastructure. I've been through that with Windows.

Re: Accept, don't fight, systemd

When it takes over file system mounting, including hiding most mount points

I can see how this is annoying, especially when you don't know what is going on, but mounting filesystems is an integral part of the startup process and therefore should be managed (in part) by systemd. It was manged using the old sysV scripts too btw, so it is consistent as far as init systems go. The difference with systemd is it actually knows what a filesystem is and that it is different from a service, so it can manage and monitor them accordingly. What this means is that filesystems associated with booting (root, swap, dev, ...) are now systemd entries instead of /etc/fstab entries. Once you realize this, it is not that hard to manage. And /etc/fstab does still work, of course, for filesystems you want to manage yourself. There are reasons you might want to create systemd entries for those too, though. Automounting, for example, is handled much better with systemd than the old autofs route that we had to use before.

But I don't see why I should need to think about let alone take care of (and most probably at some point forget one of) multiple files to handle mounting (not counting in the stupidity of searching for examples of configuration files to adapt in /usr/lib/systemd/where-the-hell-is-anything) when /etc/fstab is a perfectly fine file with everything listed nicely in one place and giving anybody with only even a little bit of *nix knowdledge a chance to do and fix things.

And as someone else said already, what's wrong with "mount -a"?!

I would object that people who admin linux systems would not readily introduce cruft that makes their system more difficult to maintain.

But we are dealing with rather big companies that make bucks with supporting linux. And GNU/Linux, unfortunately for them, was getting easier to admin. When you used to compile you have packages. Even compiling modules into the kernel is automatic with dkms now.

So the linux support companies find themselves with a problem they share with the hardware companies. GNU/Linux works too well.
One solution is to bring rockstar developers to design the parallel of the windows registry. I say rockstar in an ambivalent way. One with outstanding coding skills but with a reality distortion field so bad that when his debug flag creates problems to the kernel devs he says "fix the kernel not my problem".
WHAT?
RedHat should have told him "Now you take a CS 101 course and relearn about namespaces and about not interfering with other people already established conventions, especially if it's the fucking KERNEL, you NOOB" - of course this would be the official public watered-down response.

So, everybody is happy. Hardware companies, support companies, and the horde of developers that prefer to roll out their own stuff instead to contribute to existing projects so they get fame and maybe a few bucks.
Luckily for the user, if enough clear thinking old school hackers exist, they will modularize or come up with drop in replacement for the systemd monolith. Else, better start exploring a plan b with genode, bsd, slackware, because the windowsification of linux won't stop here.

Re: Accept, don't fight, systemd

I completely misread your comment. Sorry about that.

Short answer is, it isn't. As parent, it gets the SIGCHLD and can take action based on configuration and exit status. There is also a simple watchdog facility that depends on the application sending a "ping" to systemd within a fixed interval.

The original reason for the journal was to allow recent log data to be easily presented (i.e. without the equivalent of grepping /var/log) when running "systemctrl status ".

Implementation aside, there is significant value to having structured logging. Running a grep is fine for smaller installations, but becomes prohibitive the larger your logs grow (especially when searching through months of logs). Likewise, simple pattern matching works well in the simple case, but can failure spectacularly on unexpected input (e.g. a missing field) or on multi-line log entries (e.g. a stacktrace).

Re:Accept, don't fight, systemd

[Anonymous Coward]

In this case, it's pretty clear that, since all the major distros have accepted systemd, that it's been accepted by the majority of users and become the de facto standard. There seems to be alot of momentum behind it.

This isn't all that it seems -- for example, there has been a subtle yet constant push by systemd/redhat to make it harder and harder to use any alternative. eg, they pulled eudev into the tree (with all kinds of claims about how you can just compile it out, no worries!), creating more hardship/work/QA if you want to use it seperately. Now, they've basically said if you want to use Gnome, systemd is mandatory (and tied large parts of its functionality to it), so if you want to use Gnome you have to recreate all the work they are ripping out. It isn't cool.

Re: Accept, don't fight, systemd

I can sympathize with wanting to structure log data better, but that doesn't justify tying that into a new init. I have reservations due to accessibility as well. It is dead simple to grep text files, to split off older entries and compress them, etc. Unix has excellent tools for that. If all else fails, you can cat it to the serial port and do the analysis on a machine that isn't broken. There is no reason better structuring can't be applied to those so that they become even easier to manipulate.

One reason the early internet had so many different but compatible client and server implementations was that their protocol was human readable on the wire. You could just look at it and tell if it was correct. If something odd was happening, you could connect with telnet and step the server through the protocol manually to see what happened.

Re: Accept, don't fight, systemd

[BadDreamer]

The problem is that systemd should not do what it does to the startup process. It's taking over *everything*, and the stated reason by the lead developer is to force Linux to behave as he wants it to.

It should not mount. It should not log. It should not handle network connections. It should not automount. Those are not init tasks. Those are specialized tasks which should be performed by specialized tools.

PolicyKit specifically can be compiled to use consolekit instead of systemd for session tracking (this is actually the default, you have to explicitly compile policykit with systemd support).

Unfortunately this is kind of the downside to binary based package management. Either PolicyKit has to be modified to support both as configurable options, probably involving a maze of symlinks and wrapper scripts, or separate policykit-systemd and policykit-consolekit packages have to be provided.

If Debian has decided to to go with systemd, this is probably going to be a common issue on that distro, as when given the option of compiling something with it, they probably will.

No, the reason "everyone" choses systemD is because they don't know any better. (aka. "peer pressure") systemD is a very dangerous weed, designed and maintained by someone with a history of half-assing his projects and ignoring everyone else. It replaces and re-implements a number of well established, stable, very well understood, highly bug free (due to simplicity, and shear age of the code) software packages... that an INIT SYSTEM has no reason to be. I understand the appeal for distro maintainers... demand starting for desktop environments, built-in dependency system, etc. But for the most part, SysVinit handled everything already. (not demand start, but that's very UNIX anyway: in UNIX(tm), things start when they're configured to during boot, or when a USER f***ing starts them.)

I am extremely suspicious of so many folks with 3 digit IDs coming out strongly in favor of the inevitability of systemd.

I strongly dislike systemd and Pottering and I am shocked that Linux is evolving in this way. It seems like a concerted and coordinated effort. It seems like someone is driving a poison dagger deep into the heart of Linux.

I would be interested in hearing why exactly you are in favor of giving up the *nix way? Is "one or two levels above" really worth it when it costs so much more?

Re:Hmm

[epyT-R]

just better eh? By what standard? This is the same mentality that's overdoing the plumbing in everything else these days. The results are buggier, slower, harder to use products (phones, cars, hell anything someone's managed to cram a computer into) that cost more than they should. There's something to be said for keep it simple stupid, especially when it comes to basic functionality like init. KISS keeps it easily understood, therefore easily validated for bugs or security, and it just works.

Even with gentoo, which I have been using for many years, the python dependency of portage is strangling the software. It's slow as hell, and if something hoses the system it's likely it won't run because python and its wrappers have many dependencies. A package manager should run as a static binary if at all possible.

Re:Hmm

[Anonymous Coward]

What is, in practice, actually better about it for dat-to day use and administration?

Well for one, if your system won't boot from disk anymore, you can no longer boot from alternate media and simply cat or tail the log files to see why.
The log files are binary now, so just like on Windows, your only option is to send the logs elsewhere to be read and interpreted. But there is no option for you to know what is going on anymore no matter if you would be capable of fixing it or not.

Another improvement is legacy services which will all be disabled in the near future, as Lennart stated he will be doing.
Hope all of your software is still being maintained and was compiled in the past couple months!

Personally if I wanted my system to fight me to keep it running, I would make all the servers Windows. I see no need to take Linux down the closed source "no one but The One maintainer can read your logs" path like the other commercial unixes

Re:Hmm

[dentin]

For every complex problem, there is a solution that is simple, easy, and wrong. Bootstrap/init is a complex problem, and systemd covers more of that complexity than previous solutions.

As for the three digit UUID observation, that's because those people where there at the beginning. If they're still active today, of course they would have strong opinions - they have a lot of experience to draw on.

Re:Hmm

[Anonymous Coward]

Use paludis/cave. It's c++, with many fewer dependencies, and a much stricter interpretation of package dependencies. It can be a little annoying to use sometimes, since it's much less flexible about letting the system pass through broken states during a set of package installs. (Sometimes the tree maintainers inadvertently introduce situations where this must happen, since they don't normally test on cave, only on emerge.) In these situations, you have to study its output to see what edges in the dependency graph are causing the problem, and force cave to completely rebuild those packages and their dependents.

[rastos1]

Is it the case that as long as you don't have to deal with it and it works, then it's ok? What happens if you want to modify the service dependencies? Write your own deamon? Add some debug output here and there? Customize startup of some service?

All that currently requires me only to understand the bash syntax. In fact it currently requires only some familiarity with shell variables, "if" and "echo" and works from HP-UX, to FreeBSD, Slackware or Gentoo.

Re:Hmm

[secretagentmoof]

Those low IDs are after post-"whoops, we deleted all the accounts, sorry!" in 1998 or thereabouts. Johnny-come-lately types, really.

Re:Hmm

[deek]

Yep, it works, I don't get any headaches from running it, so therefore it is OK.

I have started to look into the workings of systemd, and it certainly seems fine for modifying service dependencies, writing my own daemon, and customising the startup (though that is a rather ambiguous phrase). I can even use a sysv init script within a systemd service file, if I wanted to. You don't need to add debug output with systemd, because you don't need to write a script to start a daemon. It just starts the daemon you configure in a service file, and logs any output. That works for me, and to be honest, is actually much simpler.

Understanding bash syntax isn't as useful on HP-UX and FreeBSD. That shell isn't guaranteed to be available. A sysv init script isn't as portable as you make it out to be, because of inconsistencies between the different systems you mentioned. Good luck getting a Slackware init script to run on HP-UX. You _could_ make a portable script, I suppose. So that is an advantage, even if it takes extra work to properly test the script on every type of system you need to run it on. But if you have any Solaris SMF systems, portability goes down the drain.

Systemd is a change in the way thing run. It takes some adjusting and getting used to. If you make the effort, you'll find that you can make it work for what you want. That's an OK in my books.

Re:Hmm

[rastos1]

I did not say that the shell scripts are portable. I just said that I can read and easily modify them on any *UX platform.

You don't need to add debug output with systemd, because you don't need to write a script to start a daemon.

You never know what someone needs. If I decide to alter iptables firewall while some VPN daemon is running, or run ftpd only when samba runs, ... my reasons can be anything and obscure. And currently it is just a script away. I have some doubts whether it will be equally easy with systemd.

Re:Hmm

[Chang]

Yes, it's in RHEL7 release candidate (GA should ship next month)

Re:Hmm

[Anonymous Coward]

You're plain wrong: bash is available at boot time on SMF systems. Religion was beaten into them, finally, and they ship GNU stuff.

Nothing stops you from building and using bash on the other systems. There weren't "portable" ways to start things at boot on vendor unix ever, and whether or not you have bash isn't the hard part of the problem. This is all a distraction.

Does SMF have value over dumb shell scripts? Yes.
Does systemd also have a similar kind of value? sounds like.
Is there a cost to the higher complexity of both? Yes.
Are there annoying things about both SMF and systemd? Yes.
Does systemd take this annoyance to an unprecedented level? oh, fuck yes.

You do not have to put up with this, so don't. You do not have to choose between shell scripts forever and systemd. You can write a new thing that has systemd's advantages without having an asshole mantainer and security-reducing mission creep. You don't have to write the thing today. You can write it tomorrow.

You *do* have to stop every damn thing from depending on systemd today, though. A web of dependencies backstopped by apathy: this is political. Don't allow it.

Re:Hmm

[Tester]

systemd's big feature of the alternatives is that is also supervises running deamons after they've been started. OpenRC (and baselayout 1.x, it's predecessor), tried to do it, but in a half-hearted way that never really worked. That why we have the "zap" command to tell the init system "you think this daemon is running, but it's actually not". With systemd, this kind of thing can no happen because it actually uses modern kernel features to keep track.

Re:Hmm

[BadDreamer]

And this is what systemd should be doing. Not running udev on its own, and mounting file systems, and handling network connections, and $DEITY knows what else garbage it's stuffing in its bloated chunk of API rot.

If systemd did init, and did it well, and did nothing else, it would be embraced by pretty much everyone who was sane. What it does now makes me wonder the sanity of anyone who embraces it.

That's not a windows issue, but a driver issue. Realtek, for example, maps the headphones as a different audio device, thus the game starts up, chooses the current device in use and won't switch if that device is no longer in use.

[steelfood]

I like how people automatically assume change == good. Maybe I'm getting old, but it seems to be a young person thing (as is the rewrite everything from scratch mentality).

Change is change. It can be good, it can be bad. I'm not an expert on such things, but from everything I've read, the change to systemd is bad. And it seems to be a bad change in much the same ways the examples of change you gave (Metro, Unity, etc.) have turned out to be bad.

The Unix philosophy has always been to do big things by using little pieces. To violate this philosophy is not necessarily bad, but it would seem like trying to fit a round peg into a square hole. Sure, if you hammer it in hard enough, the thing will fit. But your square hole might have trouble fitting square pegs through afterwards, and your wooden board might crack after you fit more things through the hole irrespective of shape.

I'd have used a car analogy, but the best I could come up with is using the wrong kind of motor oil, which when put that way, doesn't seem quite as severe as the systemd problem.

Re:SysV is likely to always be supported

[sjames]

Systemd COULD be a good thing if it would stick to starting up the system. It should START udevd, not BE udevd. It should START dbus, not BE dbus. It should be trivially easy to do any of:

Switch from systemd to SysV, switch from SysV to systemd, use systemd but honor the SysV init scripts. With a bit of work fron the systemd folks, it should even be fairly easy to use SysV and have it start systemd to monitor select daemons.

Do that and every single objection would go away immediately.

Re:SysV is likely to always be supported

It's not really recreating Windows. However it is recreating the bloat and interdepency of everything that Windows has. Can you really call modern Linux systems lean and mean anymore?

Re:SysV is likely to always be supported

[thegarbz]

A lot of the people who complain specific changes are bad often do so because they are blinded to the cases where the original system is actually broken and a rewrite from scratch is the best option.

I'm not saying here that systemd is good, I'm saying that the init system is damn broken when it comes to modern use case. It started being broken in the era of hotplugging and when Linux started migrating from the serverroom to the desktop. I'm also reminded of who people complain about PulseAudio and Wayland. Yes they aren't perfect but good luck getting a bluetooth headset to *just work* without PulseAudio, and likewise good luck simply running up to any old projector with your laptop on X11 and expecting it to work magically.

Tools have their place. The classical init system is still a great tool for a server machine and it makes little sense to move from it, likewise so is X11. However as times change and we find derivatives of Linux in small portable devices that need to sleep most of their life and yet be up and interacting at the push of a button, and as such the programming priorities to support those devices change too, i.e. parallel startup of system services in systemd which as far as I can tell the classic init system isn't capable of.

Change can be both good and bad at the same time. I look forward to the classic init system going the way of the dodo, but I'm also thankful it exists the way it does on my server.

Re:SysV is likely to always be supported

[BadDreamer]

And I wish people who think that change is good just because it's change would have to deal with the real world consequences of such a foolish attitude.

Re:I wrote OpenRC

[crow]

Thanks for OpenRC. I *love* how it works on my Gentoo system. The ability to load custom variables for any script with /etc/conf.d files is wonderful.

I've gone a bit crazy with my /etc/conf.d/net, automatically setting up a ssh tunnel home if it sees that it's on an outside network (and trying several methods to get the tunnel working). If it's on ethernet, it switches the WiFi to being an access point. Lots of fun. I just wish the preup()/postup() functions were part of all the init scripts, not just the net script.

I also make use of /lib/dhcpcd-hooks to clean things up if the local network is unfriendly. If the provided DNS server mangles entries for non-existent domains, and if it doesn't block Google, it switches over transparently in my local script.

The paradigm of letting the user modify the behavior through regular shell scripts is extremely powerful. Thanks for keeping it alive.

When I compare how nice OpenRC is with Debian's setup, I could understand why they'd cry for something new.

I do wish they had given OpenRC more of a fair shake. Not only is it cleaner than systemd, but the upstream is much more decent.

Re:I wrote OpenRC

Roy (UberLord), I am very truly grateful to you. I don't know what occasioned your ceasing to be a Gentoo developer, but I thank you for your contributions of OpenRC and dhcpcd--and of your continued presence in the Gentoo forums.

Too much integration

[Anonymous Coward]

with Gnome and other bits for my liking. This is like PulseAudio. It's not that good and it seems everyone is adopting it. The issue with FOSS is the desire for change that is too quick rather than fixing what works. LILO, for example. While GRUB is great, LILO worked fine for me and in fact, it still used by many distros. FOSS has become bloated like its commercial counterpart.

Recently I installed the still-in-alpha Haiku OS because I miss BeOS (still). The entire OS installed in less than 2 minutes. Talk about *fast*. It it were not for the lack of decent software, I would make the move today. Haikuware does have some great software, though. BeOS was awesome and kept it simple. Written from the ground up to remove the mistakes traditional UNIX and Linux were/are still making.

Re:Too much integration

[Cramer]

To be fair, LILO is very primitive and sensitive. It doesn't read filesystems; it has an installed map (the result of running lilo) that lists the exact blocks to load for a given entry. You cannot load anything that's not in its map. Touch any of those blocks and it can fall apart. GRUB was a vast improvement, but also adds a great deal of complexity. (GRUB2 even more so.)

Re:Too much integration

[allo]

grub 1 was great, you could install it with a few basic commands from the grubshell (which was in the terminal just like during the boot). grub2 needs config generation and actual use of grub-install.
(But it works okay, too)

Re:Too much integration

[whois]

It installed in less than 2 minutes because there is no software, as you stated in your post.

I use debian preseed and install my systems via PXE in 5 minutes. Of course I tell it not to install any software, so that is part of the reason it installs quickly. The other part being that it doesn't have to ask questions. We could get that time down a bunch by throwing away compatibility with 90% of the hardware. Solaris on Sun hardware used to install relatively quickly, and was very reliable (in some ways) because they always knew what hardware was there.

Honestly, on a workstation boot time is 1000% more important to me than install time. If windows 8 takes 45 minutes to install and boots in 3 seconds then fine, I'll accept a windows update if I'm not doing anything at the moment. If Linux can install in 5 minutes but takes 2 minutes to reboot then I don't want to reboot. Which is fine unless I'm using a laptop..

Re:Too much integration

Fuck Haiku. Those douche bags STILL refuse to go 64 bit. They are a bunch of idiots living 20 years in the past.

Strictly speaking, grub 2 does not require config generation, it's just that nobody but the actual grub 2 manual mentions the fact that you can still manually write configuration entries.

Re:Too much integration

[thegarbz]

Bloat != larger useful feature list.

Citing GRUB as bloat over LILO is a great example of misusing the word. I wouldn't call GRUB bloated, I would call LILO primitive. There are lots of things you can do and many things people want to do that GRUB is capable of but LILO isn't. That isn't bloat. Bloat would be LILO being the same size as GRUB without any added features that people use.

The same really applies to this discussion. People talk about init as if it isn't something that could be vastly improved. It is. The inability to start multiple services at the same time, track dependencies between services, and drive processes through an event screams of 80s era thinking, a time when things were simpler. No hot-pluggable devices, no pesky end users wanting things like a fast responsive machine, just a basic system requiring a beard of wisdom to run. (Even above one of the rebuttals to init's lack of features was that the person clearly doesn't know how to use init). Should we need to?

If you want a lack of bloat then go download RedHat 3 or some other ancient system. But then don't come and expect your Bluetooth headset to seamlessly work when you plug it in. Like it or not, Linux and Unix aren't solely in the domain of the server room any-more. That's not bloat, that's support.

Re:Too much integration

[aNonnyMouseCowered]

"The entire OS installed in less than 2 minutes. Talk about *fast*. It it were not for the lack of decent software, I would make the move today."

Not surprised. Less software to install = faster time to install.

Re:Too much integration

Neither does GRUB 1. And in fact, both are usable with any config file. It's just that every distro out there has means for automatic generation of grub.cfg (menu.lst) to support random kernel packages.

[Junta]

There are significant numbers of people who understand it just perfectly and have valid criticisms that are not bugs.

http://ewontfix.com/14/

The systemd team has pissed of Torvalds:
https://lwn.net/Articles/59368...

Additionally, they repeatedly deny that anyone should have a text log for any reason, dismissing criticisms as 'just hook in syslog *too* as an *optional* thing'. Basically systemd discards decades of sensibilities ecosystem to 'do it better', while throwing out the baby with the bathwater (ditching modularity and portable log data and such).

It's not just that 'if you don't like it, fix it'. People don't like the very fundamental aspects of the design that the systemd did *on purpose*.

Re:No...

[Anonymous Coward]

The ewontfix.com/14 article is full of factual errors and was rebunked several times by more knowlegable people. And Linus is pretty easy to piss off, what does that prove?

"If you do not like it, fix it" is still valid. Systemd did up the ante, so it is indeed more work to provide a complete replacement of systemd than it was for systemd to replace sysv init. But then systemd would indeed be poor if it did not provide benefits over previous implementations.

What really amazes me is that people ranting about software starting to depend on systemd does so just to annoy them personally. That is completely stupid: The software depends on systemd since it solves real problems that software used to be facing. When a wide group of developers sees value in using systemd, then maybe reading up on it (past the point where you go "oh, we never did it like that before") might be warranted?

Re:No...

[epyT-R]

Whether it upped the ante or not is a subjective judgment. In this case, 'fixing' would require reengineering it from scratch. Why, when openRC and friends work just fine?

Re:No...

[Anonymous Coward]

Because openRC is not even in the same league as upstart. And systemd leaves upstart in the dust -- which is why debian went for that instead of upstart. Read the technical comitees findings: Most TC members wrote a summary explaining their decisions and those are really full of good technical information. There is a lot of cruft in between those posts though.

If you do not believe me or think the Debian technical comitee to be biased: Read up on why the people responsible for the software that now moves to depend on systemd do that. Most did provide a solid reasoning for their decision. One argument is that it is available everywhere, but then there is the great cgroup stuff (systemd can reliably stop services incl. all their children -- finally), security features (like private temp dirs for services, etc.) that are really easy to do, simple configuration language for the services (*way* simpler than sysv init scripts), proper logs for everything, simpler debugging of services (the status output of the service contains the last log lines -- you do get used to that really fast!).

Could all that be implemented in a different way? Sure. But nobody did it yet. Maybe openRC will at some point implement all that and be a serious contender? I doubt it, but who knows.

Re:No...

Torvalds is pissed off at Kay Sievers, not at systemd and not at the systemd team. He's fine with Greg Kroah-Hartman taking over that mess until Sievers can get his shit together. I went through the original bug report and the kernel mailing list discussion when it first caught the limelight, and I think you're seeing Sievers's actions (condemnable as they are) as representative of the whole systemd team.

Re:No...

[ceztko]

ewontfix article has been demystified several times. Instead of pointing you links of commentary against it, I prompt you to read it carefully. The author is basically saying: we shouldn't take the risk of writing complex software. Because it's complex it can be security flawed and it can breaks the system if we introduce bugs. Let's keep a minimal init and continue as we always did. What the author is not saying is that the init software of modern operating systems have to be complex, because we expect it to have more features so it will be practically more reliable: I expect filesystems to mount reliably at boot, and services depending on filesystems mount or network resources to start reliably and with no race condition being possible. cgroups is a way to ensure all processes of a service are grouped and can be killed all together, without a single one "escaping". Simple, minimal, compact init systems *can't* ensure this. The shame is that upstart itself can't ensure this basic stuff: with regard to these aspects it still has an enormous amount of bugs that has never been fixed. #406397 to name one: confirmed and never fixed in almost 5 years, and also not taken much seriously because it would be the admission that upstart just can't reliably stop the services it starts. Also, the arguments of the author are very poor with regard to the upgrade/reboot controversy. Saying that it's complex, so it will need upgrades, so it will introduce bugs that brick the system or force me to reboot the system is just like saying: we are monkeys, we are idiots, and we should do nothing complicated because we would do it wrong it anyway. I'm a software engineer and this is the most foolish argument, and what is even more sad is that I continue to hear it. My experience tells me a completely different story: we can be smart, we can conceive and code very complicated stuff that will solve a wide range of problems, that will work as expected in most practical situations and have extremely low amount of bugs. At the same time it can be very elegant and coded cleanly. It's only about discipline, quality expectation and, more important, testing.

Re:No...

[t_hunger]

If you think sysv init is not broken, then you must not have been using unix systems in earnest.

It is only simple till you want to have a reliable boot without races... BSD init is way simpler, true, but then that was deemed to be too inflexible already in the golden times of Unix. You really want to go back to that? Seriously?

You are aware that udev is part of that tree you are proposing to delete? With eSATA harddrives coming and going, projectors that get attached at random times, all kinds of gadgets with USB connectors? No thanks, I want something that I do not need to change a the boot script and then reboot when I plug in a mouse.

Let me keep systemd and go straight for a beer instead of bombing my system back into the 60s.

That way I can also update all the software I care about (much of it already depends on systemd or will do so soon), I get
* the journal instead of a set of randomly formatted text-dumps all over /var/log,
* a convenient way to kill apache with all the crap that it started,
* a more robust boot process that is not sprinkled with sleep 5 statements to give daemons enough time to be fully up before bringing up services that depend on them being there.
* a more secure system by being able to isolate daemons from one another and the rest of the system.
* a lot of convenient system config tools that work on (almost) all modern Linux distributions and do so even better that the "do one thing and do it well" tools that got replaced by them

a more robust boot process that is not sprinkled with sleep 5 statements to give daemons enough time to be fully up before bringing up services that depend on them being there.

Usually the sleeps are for hardware settling, not for script startup. Eg. when you plug a USB device that may take a couple of seconds to be available after powering on. This will be needed *regardless* of what script is running the show. And dependency management on start scripts is a solved problem. Have a look at FreeBSD/NetBSD rc.d system, or Solaris SMF.

A huge regression. Replacing a simple, robust, well supported system with something overly complicated is NOT a gain for me.

Something wrong with apachectl stop?

A far less secure system actually. Without it, the only real attack front is sshd. With it, we suddenly have another front to worry about - and an attack here is likely to be much more damaging.

At the very least they are way more consistent in how they work and they work on all modern Linux distros in the same way. That was never possible before.

[RabidReindeer]

I just spent a merry 45 minutes trying to get Fedora 20 back up and running after a reboot. Systemd kept knocking it into Emergency Mode with no indication as to why. I'm still not certain whether it was a failing mount or a video card acting up. Or something else I don't know about yet.

SysV init is unquestionably feeble when it comes to controlling systems with complex daemon interdependencies. But putting stuff into sealed packages with No User Serviceable Parts Inside is not the way to go. I had to deal with that under OS/2 and it's one of the things I hated most about OS/2.

There is a tendency these days to offer a "complete solution" and to sneer at the ungrateful unwashed masses. But complete solutions never turn out to be complete enough. And these "Complete Solutions" are infamous for eliminating popular features that were in their predecessors. The systemctl facility admits that there are certain things that it cannot at present do that the cruder, but more flexible scripts of SystemV supported, and it's far from the worst offender.

Unix was developed on the philosophy that you didn't attempt to make one program do everything, you strung together simpler tools. Likewise, it logged to plain text files, which makes them accessible to a whole raft of text utilities, instead of a handful of specialized log utilities a la IBM. Besides which, a text file has to be seriously mangled before it's totally useless when everything's shot to Hell. Most binary files break far more easily and are far harder to repair.

Well, ok. My computer boots fast enough without it, thanks.

Systemd can set up filesystems without racing, something that is not possible with sysv init. No more races makes for a more robust boot. In fact systemd does address most of the race issues found in the debian init system. Go and check their bug tracker if you do not believe me.

That you were unable to configure your system to make it boot with systemd is anecdotal evidence at best. I bet it did not boot right away when you installed your first sysv-init based Linux ever either;-)

I never measured the boot up times, so I am not sure whether systemd is faster or not. I frankly do not care one way or the other.

"a more secure system by being able to isolate daemons from one another and the rest of the system."

A far less secure system actually. Without it, the only real attack front is sshd. With it, we suddenly have another front to worry about - and an attack here is likely to be much more damaging.

At least here systemd has no open ports. Why does it matter whether systemd, upstart, sysv init or openrc started the sshd under attack?

With the options to limit the process that systemd offers I can even severely limit what an attacker can do on my system once a daemon is compromised. Those countermeasures are of course also possible with init-scripts, but they are *way* harder to implement securely. I have not seen many distributions that bothered to add any additional security measures to their init scripts.

A local user is something different, true, but considering that you are referring to sshd that does not seem to be your argument.

"a lot of convenient system config tools that work on (almost) all modern Linux distributions and do so even better that the "do one thing and do it well" tools that got replaced by them"

2) systemd is... what? Something sensible that at least attempts to start & stop services in a standard way?

And then, into this, comments such as yours are thrown:

No it hasn't. Process ID 1 should do very little. That has always been the premise of init systems. When you've got something that does the exact opposite then you've got a problem.

When I see a statement like that I think to myself - why. What is sacred about PID 1? Why should it do very little? How is this a premise of an init system? And would you be happier if PID1 launched systemd as, I don't know, PID2, and then did very little?

I really seems to me that getting rid of that horrible kludge of shellscripts and moving towards a standardised and sensible startup process is a big step forwards in Linux land.

I became obvious to me with the comment of "a convenient way to kill apache with all the crap it started" that the commenter has no idea how to manage a unix system - unix has never been about "convenient" ways to do things, or "one big monolithic sysinit system", but rather small but powerful tools that can be strung together in many useful ways.

If you want "convenient", use windows or stay in the Kde/Gnome/whatever GUI, you have no business being a sysadmin.

"That kill apache, not the crap it started and that forked itself away."

I cant be completely sure here, but there is a funny pattern I have noticed over the years that may explain your experience. Over and over again, I hear about problems that require these over-engineered solutions from people running over-engineered distros that I just cannot reproduce using my (cleaner) system. So I suspect somewhere in your excessively complex system you have managed to break apache in a way that I cannot reproduce using a simpler system.

And yet this is an argument for introducing yet more excessive complexity to remedy? Doesnt make sense to me.

"Systemd can set up filesystems without racing, something that is not possible with sysv init. No more races makes for a more robust boot. In fact systemd does address most of the race issues found in the debian init system. Go and check their bug tracker if you do not believe me."

Why would I care? I dont use that system and am not affected by their bugs.

I don't see how systemd could be any better at stopping runaway/zombie'd processes than the kill command. The cgroup stuff is interesting, but not worth the rest of the complexity. I don't think anyone is saying that sysV init is perfect, but that it is good enough to do what needs doing without being over complicated. In terms of 'proper logs', to me a proper log is a text file that can be easily searched without using some fumble fuck interface that reminds me of event viewer in windows or it's horrid powershell command line backend.

- a less secure system because you can't get logs, and lose log information, and can't debug problems due to timing failures caused by the rest of the system
- a lot of inconvenient system config tools that don't always work, or do the wrong thing sometimes. The "do one thing and do it well" tools got replaced by tools that try to do everything, none of them done very well.

Not to mention that a network analysis tool that cannot solve the NP problem that is part of network analysis...

And the constant patching of services because systemd can't properly schedule services...

Just adding a new service to a startup can spawn all kinds of failures due to the inability to handle a specified order...

On the other hand socket activation is not to the best of my knowledge supported, but I think that's a good thing. What a horrible hack! They took something very simple, logical, and robust (serial activation of services) and made it orders of magnitude more complicated, doubtless creating bugs that we will be discovering for many years to come in the process, and for what? To shave 5 seconds off a task that that you might need to do once a year? In what twisted alternate reality would this possibly seem like a good idea to anyone?

These features alone remove plenty of race conditions in services life cycle.

You know what is even more effective at removing race conditions? Serial activation. And all it costs is a few extra seconds in the rare event of a reboot.

Did someone tell you "script" is a bad word?

You have a choice to keep this represented in a higher layer (text file scripts laid out sensibly written in a high-level architecture-independent language), or as a set of compiled binaries forming a monolithic Windows-style system with a multiplicity of hidden inference rules.

And the current init files can be improved if you don't like the layout or want to make new facilities available - do you think it's impossible to add dependency graph tracking in a way that is accessible to scripts rather than having a "registry"?

Systemd is not the only choice GNU/Linux has. Just because systemd is a Red Hat funded project, and is being adopted by the mainstream distributions, doesn't mean it's the only choice. Small, unfounded, and non-mainstream software also exists that is available but isn't widely used because any number of reasons.

Over at LinuxQuestions several guys have been experimenting with finally getting a full port of Gerrit Pape's Runit init and daemon manager ready for mainstream usage alongside Eudev which they completed work on a while ago, and was actually published in the LFS-Dev book.

These guys are just users and system admins who, from reading their work, are sick of the hype, lies, and misinformation surrounding the fanboyism and propaganda being promoted by the pro-systemd crowd, and honestly, who can blame them? But these guys are making a difference by actually trying something different.

It's sad only three people are even working on the Runit effort for LFS as a complete fully featured and functional alternative and successor to sysvinit. LFS software can be fully transported out into any Linux distribution. Maybe if they had more help, systemd would be just another alternative, but I guess people are willing to drink the koolaid no matter how much poison it contains.

No it one of systemd's goals to manage a system reliably.

Processes that double fork end up with the init process as its parent in the process tree: That is unix-philosophy at work and apache is not to blame here.

That makes it really hard to manage things like apache without additional concepts like cgroups. Those are actually not complex nor do they require lots of code to be implemented, but they need to be managed in a central place to be useful. So systemd does that right in the init process so that you get maximum benefit from the concept.

So please enlighten me: How do you kill apache with all the php/ruby/whatnot crap it directly or indirectly spawned? With systemd it is just one convenient systemctl stop apache

Well, you do *mention* apache, so the most common approach is to just kill the master process, and all the child processes die. You know, unix systems. In case of apache, you even have an utility for it - apachectl. Other approaches would be 'service apache22 stop', kill -TERM `cat /path_to_apache_pidfile`, and of course, kill -9 $(ps -ef |grep apache2 |grep -v grep| awk '{print $2}') or any other variant (eg. in freebsd you could do a ps ax | grep Ss | grep httpd to determine the master apache process and its pid to kill). On many linux systems, you also have killall and/or pkill, that will achieve the same effect by process name, and easily usable with apache, nginx and the cgi wrappers you may have running.

I was more thinking about starting postgres before the server that uses that DB to store its stuff. Grep for "sleep" in the init scripts of the sysv-init distribution of your choice: You will be surprised.

I did. FreeBSD 9.2. Most of the sleeps are for hardware settling. Replacing a shellscript sleep() with a binary version of it is not a solution anyway. Both rc.d and init.d approaches allows you to prioritize script startup, to achieve that same effect. In FreeBSD, the rcorder (http://www.freebsd.org/cgi/man.cgi?query=rcorder&sektion=8) allows you to quickly visualize service dependencies. In OpenBSD I specify in rc.local the order I want my stuff to start. I'm assuming other systems provide vaguely the same funcionality, its not rocket science. (Again, a solved problem).

Convenient for everybody. Just try the things that come with systemd. Most are a real improvement over the existing tools to manage hostname/date/time/timezone/locale/service/network/efi boot loader/virtual machine/whatnot. At the very least they are way more consistent in how they work and they work on all modern Linux distros in the same way. That was never possible before.

I'm not against uniformization. What I don't see is the need for yet another tool that fragments even more the available options. And uniformization is pretty common in other operating systems - check eg. FreeBSD and OpenBSD: they are quite different in terms of setup, but not that different. Its not like it wasn't possible before. That approach exists for decades.

Check out http://www.freedesktop.org/sof... [freedesktop.org] , especially all the options starting with "Private" there.

It sounds like a meta-version of linux containers. Why would I want that implicit on a startup script? Its about doing one task and doing it good.

Yes, I know: Just suggesting to look into systemd is sacrelegious:-) Sorry, I won't do that again.

You did not suggest. You touted it as solution to problems that, frankly, do not exist. It may have features that are very helpful, it may solve a lot of problems, but you mentioned none. Not one valid existing problem.

I think you've lost sight of the purpose of an OS and the purpose of logs. An OS is not running for the sake of running an OS, and logs are not persistent structured application data, but ad-hoc information about the behaviour of the system for human consumption.

I am not talking about structured application data, I am talking about facts that go with the actual log message like the timestamp, the PID that the message originated from, the capabilities the process has that originated the message, the full filename of the process running, which cgroup the message originated from, which boot id this message belongs to (really nice if you want to see one boot/run/shutdown cycle only), that kind of data.

Having that information in the journal is really nice. Not having to parse it out of some textfile where some application put it in a more or less randomly selected format is even nicer. Correlating data from different log files written by different applications is a huge pain that is completely gone with journald.

They need to be filtered, sliced, and flattened as needed *post-facto* to be of any use. Given that you don't even know what I want to log, from where, how is that going to be normalised in a centralized journal?

Yeap, it does. It makes full use of all the extra data it adds to the log entries and thus allows for way more reliable and powerful filtering, slicing and dicing:-)

Over and over again, I hear about problems that require these over-engineered solutions from people running over-engineered distros that I just cannot reproduce using my (cleaner) system. So I suspect somewhere in your excessively complex system you have managed to break apache in a way that I cannot reproduce using a simpler system.

Considering that reparenting processes that double fork is tried and true unix philosophy: It would be somewhat surprising to see apachectl properly clean up after itself in your so called cleaner system. Maybe you just fail to properly recreate the problems in your trimmed down universe?

And yet this is an argument for introducing yet more excessive complexity to remedy? Doesnt make sense to me.

None of the init systems currently in use is conceptually very complex. In the end sysv init is actually one of the more complex ones. The others are of course different, but I would not actually call them conceptually more complex.

In fact setting up a service and then starting it is significantly simpler with systemd (and upstart and openrc) than it is with sysv init. Give it a try before complaining about it.

Why would I care? I dont use that system and am not affected by their bugs.

Hmmm... why would you? Maybe because these are fundamental issues with how sysv init works?

Re:No...

You can wire up syslog to the journal.

I don't want to, I don't need to. I just want every bit of information a horribly broken system is still able to tell me about its state. This won't work better is you move away from plain text. - BTW: How do you use remote logging with systemd? Sending and receiving?

So please enlighten me: How do you kill apache with all the php/ruby/whatnot crap it directly or indirectly spawned?

apachectl stop

Yes, really. This is not the most simple setup here (suexec php5/fastcgi), but starting/stopping of the spawned php servers has never been an issue, even without systemd.

Please do not assume that I am too young or too stupid to know the good old ways.

Admittedly, you are making that hard to believe when you even have issues with stopping apache. There is no problem to fix.

Grep for "sleep" in the init scripts of the sysv-init distribution of your choice: You will be surprised.

Not really. A few sleep 1, speech-dispatcher has a sleep 3 and stunnel4 sleep 5. Both at restart. I couldn't care less.

By the way, there are alternatives to sysv init. They work well and don't even break compatibility. They are what systemd needs to be compared to.

Let's just wait a year or two. By then all the hotheads that are running for the BSDs now will be back

Linux and Free Software are about modularity and choice. Large-scale breaking of backward compatibility and user expectations for dubious reasons is not going to play well with the community. Linux is already getting WAY too complex for people concerned with security, and additional complexity in form of enforced blessings by a group of people who comes across as conspirators gives me a very bad feeling. Who profits from intentionally weeding out choice? We'll see, but don't expect me to wait for it.

Re:No...

[discord5]

I was more thinking about starting postgres before the server that uses that DB to store its stuff.

Allow to go off on a tangent here, but most of the setups I deal with keep databases and webservers on separate machines. Today we've got virtual machines coming out of our collective asses so even developers start separating their services from each other. What you're talking about is dependencies and how to deal with failure of a service. That goes far beyond the scope of what systemd can provide, since it's so cheap and easy to run stuff on different (virtual) machines these days. However, I realize that you're using this as an example, so I won't really press on the matter other than that this is the poorest example you can choose.

But it does speak to part of the problem. All I continuously hear about systemd as the greatest advantage is solving the "complex boot order" dependency problem, parallelizing boot scripts and decreasing boot-time. To me, as a sysadmin: I DON'T care. I'm pretty sure that 90% of the servers I have running take a longer time in POST than they do in booting. If I reboot something, I'm taking it OFFLINE. I'm not sitting there crossing my fingers "Please come up quickly", but I've got a failover setup and another machine has taken over before the server is rebooting. And "complex boot order" really? Is that really that big of a concern? I really hope you don't have to manage 500+ servers then, because you'll be in for a surprise on complexity.

This brings me to interesting questions that I hear nobody talk about. If you're doing failover type of things, you're bound to end up with heartbeat/corosync/... + pacemaker & co. As a sysadmin, for me those things are extremely important. Last time I checked (and granted, that was a while ago), none of these actually had a proper way to deal with the impact of systemd. I'm sure that the people behind the various failover solutions are working on it, but last time I checked I saw very little in official documentation, and only the occasional headscratching on mailinglists.

To me, systemd presents quite the challenge, with consequences even outside of the technical side of things. For a while I'm going to end up in a mixed environment, forced to write two sets of operational procedures, disaster recovery scenarios, etc etc. I'm going to have to retrain people on how to read system logs, have to deal with systemd's quircks (no offence, all software has its peculiarities, and so will systemd), and will probably have to completely rethink how we do failover scenarios. And all I gain, what I'm really interested in is... cgroups...

Projectors, usb disks and sticks, whatever ... Those things have no place in a serverroom, and I don't care about it. And let's be frank, nobody in a corporate environment gives a shit about linux on the desktop. The few companies that I've been at that have linux on their desktop are small businesses with a near complete tech workforce.

Why would you want to convert rich information into a string and shove it down a pipe before you make use of it?

I think I know the answer to that question. Some environments need to archive their logs, for a long long time. Some things are more complex than a "simple" local syslog setup, and with that complexity comes a set of tools that often organically grows over the years or follows certain administrative procedures inside a company. In such environments, change is a difficult process, not because of people but because of corporate inertia and red tape bullshit. And it's great that systemd provides a syslog fallback for us text-junkies, at the very least it buys time...

The other side of the medal however is, nobody is really having a problem with text logfiles. The examples I continuously see are so contrived, or focussed on "the linux newbie" that it just reeks of a developer looking for something to do. My biggest frustration with lo

The comments section of that article makes that clear and it makes it clear that those behind systemd have no idea how a Unix style system should work, and why. Hint: Poorly documented, bullshit XML schemas have no place anywhere near there. Linus, Ingo Molnar and Ted Tso have all made their positions crystal clear on the style and maintainership of that piece of software and the people behind it. As Ted Tso put it:

Re:No...

[segedunum]

When I see a statement like that I think to myself - why.

The fact that you have to even ask that means that you will never get it. When you have an init process that feels the need to do a whole lot more you have several times the bugs, and this is a system you're relying on to boot a system - which you're then going to have to troubleshoot. As a system administrator it fills me with absolute dread.

I really seems to me that getting rid of that horrible kludge of shellscripts and moving towards a standardised and sensible startup process is a big step forwards in Linux land.

Shell scripts are human readable, they work and they stand independently so if something fails, most of the time, it won't affect anything else. In a systemd system you won't have the faintest idea what s going to happen. There is no reason a more sane init system could not be developed that used human readable scripts and logs, and we certainly don't need systemd to get there.

Precisely why some of us run critical services under Daemontools ... simple, clean, and reliable. Its logging concept is a vast improvement over syslog for local logging, and if you're not into it, it doesn't force you to use it at all.

Hah! Gentoo will most likely be using it, but because Gnome literally has mandated its use if you want to use Gnome Desktop, even just for logging into it, and that's after eudev and other things. Without these things, let alone the other stuff I'm sure they'll push, things would probably be different. It's pretty slimy, as this is about politics and business agenda maneuvering rather than what's best for the community. (eg, if you are say, Red Hat, and you make it so x is the defacto standard, and someone can't use y or z without using x, you are now in the drivers seat for every and all linux variant)

Linux no longer wants to even look like Unix

[Anonymous Coward]

Your immediate recourse is, indeed, to try and sample the *BSD offerings. Their rc.conf approach I find a lot simpler to deal with than sysv's kludgy linkfarming ever was. It works very well without imposing all sorts of requirements on the rest of the system.

But the problem is political, and so the solution isn't technical. On the political side, I'm highly annoyed by the approach that resulted in this damage, but it's actually endemic in the linux world: Identify problem, then go berserk on the over-re-design-engineering like you're deliberately aiming for a strong case of second-system effect. One (and my pet-) example is the "better replacements" to their broken ifconfig, incompatible with everyone else (and three mutually incompatible attempts down the road there's no end in sight), but there are many more. The latest batch just have taken the previous failures to new heights of technically working incompetence.

What is new-ish is that the damage is spreading, in the sense that by design systemd is linux-only yet now various programs that previously worked on Unix in general are starting to depend on it. Apparently a certain bunch of influential people in the linux-sphere want to become their own vendor-lock-in-enabled bubble, to be the next redmond. This is... not good.

There really is very little recourse other than starting your own lobby war to stop the bunch. Because the problem is mostly politican, the technical side is but a symptom, almost a sideshow.

Without political pressure, soon linux will be akin to macosx, except with poorer code quality and less unified design: Technically some Unix-heritage, in practice it's its own thing, incompatible with the world. So if you'd like a Unix, your route is to *BSD. If not, you can stay and put up with the slowly mounting pile of crap of which systemd is but one thing, if possibly a tipping point-inducing thing. The *BSD people will still have to find some sort of answer, and soon, or they'll have to decide that everything depending on systemd+friends will be a lost cause anyhow and find alternative software with similar functionality, for the current crop no longer works outside of this brave new linux.

Maybe this is a problem inherent in open source? Someone idealistic has an idea and is allowed to run with it, find other likeminded people, and so on. Whereas in the corporate world you often have managers what will try to keep the teams focused and steer them in directions that will improve the products or implement what the customers are actually asking for. I have seen some new hire junior programmers who start off the first week with lots of ideas that they think are awesome ("let's rewrite everything in this new cool language!") but which are impractical or irrelevant to the product lines.

You do realize that the source to Gnome 2, sysvinit, arts, and the rest are all still available, right? Nothing is stopping anybody from making another Gnome 2 release.

If you want people to write you free software, then you are going to have to be content with what they give you.

Slight correction - they direct people to implement what the customers are actually PAYING for. If you want to change the direction of FOSS, just hire a team of developers to do whatever you want with it, and they'll do whatever you ask them to as long as the paychecks keep coming.

I don't think so. Plenty open source software is well-behaved. Some open source projects even are well-organised and have competent leadership. And it's not limited to open source, see eg. "the ribbon" or just all of windows 8.

What is apparently happening is groupthink along lines that are violently at odds with the design principles that underpin Unix, mixed with so much arrogance that everyone not using linux is completely ignored and any naysayers using linux are told to shut up and to get with the times. As if theirs is the only possibly true way forward.

This groupthink is not constructive, but I don't think it is inherent in open source either. It's just this group busily proving themselves to be unworthy of the influence they manage to have. What's puzzling is how they managed to get that influence in the first place.

Slackware

[syzler]

Slackware is an alternative mainstream Linux distribution which does not use systemd. Instead of systemd, it uses a combination of custom rc scripts and sysvinit. If Slackware ever adopts systemd as the default system init, they would likely lose most of their user base.

Slackware

[Anonymous Coward]

If you really must avoid systemd, then Slackware is probably the way to go. Alternatively, FreeBSD/PC-BSD are prettly much safe from ever getting systemd. For now you could stick with Debian Stable or Ubuntu LTS, both of them will run for years on the older init systems. So, really, you are pretty safe from systemd for at least three to five years, even in the Debian/Ubuntu corner of the Linux ecosystem.

But, really, you might ask yourself why go to all the trouble? Is it a philosophy issue? Is it just hating change? Is there something technical causing problems with your computer that is caused by systemd? A lot of people claim to hate it, but rarely give any practical reasons. Sure, there are plenty of philosophical issues with systemd (and lots of personal issues where its developers are concerned), but take a good long look at why you don't like systemd before you try to avoid it.

Confused

[ThisIsSaei2561]

I'm not sure what the issue is here.

If you're looking to avoid using systemd, move to a distro that doesn't use systemd. (I think Mint still uses upstart and Gentoo uses openrc.) Otherwise, do the legwork to support the init system you want to use.

Re:Confused

[Anonymous Coward]

Mint doesn't differ significantly from its Ubuntu upstream, and Ubuntu itself will be following Debian's decision to use systemd. Only wait a few releases and systemd will be well-entrenched in Mint too.

Gentoo will probably stick with OpenRC as a default for a while, but it supports using systemd as an alternative.

Re:Confused

[epyT-R]

It is not a static situation. There is an overt attempt to force the community to use something that violates a lot of long standing design principles (KISS, readability etc).. Just because they're old doesn't mean they're not still relevant. I happen to think they're the reason unix is a lot more robust than other operating systems.

same boat for a lot of Linux users.

[nimbius]

Im currently running Gentoo. it offers systemd as a package and ive even run it a few times with success. What it offers, along with uefi, is a chance to drastically speed up the boot process but at a cost to the Linux ethos of 'do one thing and do it well.' Im just as conflicted, and seeing as i work in a RedHat shop i fear ill have to start using it eventually. TFA from sporkbox in the summary highlights the major pain points of systemd quite nicely but the other problem it poses is the homogenization of linux and what that means to numerous Linux community members personally. Linux used to be about choice, but so many distros are systemd/gnome/networkmangler now that its almost horrifying. I get that a unified platform is the key to a 'year of the linux desktop' but the sense of alienation and loss that systemd imparts is very palpable for many of us.

Back on topic though, Gentoos commitment to choice means you can run OpenRC. Its a fine time-tested alternative to SystemDoEverything and while your coworkers might be confused by it, at least you wont have to hack through binlogs for ages to fix a problem in it. You're best not trying to hack out systemd or any of its dependencies in distros like Fedora or Ubuntu as theyre basically so intrinsic to the OS as to render it useless if removed.

Sorry i cant offer more closure for the issue, I hope someone in the thread can though. For me i worry in another ten years ill be deploying machines that are exclusively systemd, quietly muttering the free software lyric, 'You'll be free, hackers, you'll be free.'

Using the term "SystemDoEverything" just means you've bought into the hype of the naysayers without actually understanding anything about what systemd does. That's too bad. In reality, systemd completely embraces the time-honored unix concept of "Do one thing, and do it well." If you actually look at systemd, you'll see that there is no One Binary That Does Everything. Systemd is a pretty big collection of binaries, that each do one thing really well.

I am doing embedded engineering and have implemented systemd across all of my embedded projects now (4 separate projects in total, each massively business critical). I have seen huge improvements in traceability of the boot process, speed, correctness and am overall very pleased. I also appreciate that it is *highly* modular. Anything you don't like, just don't compile it. We now get process monitoring and restart for free (used to be a separate, buggy, daemon).

Overall, when I read any of these threads, I typically just see people repeating the same tired old crap and they have obviously not done any research because most of the main points are simply not true.

The point isn't about individual binaries, it's about being able to use different implementations interchangeably. Go ahead and try to run systemd without journald. Or run logind without systemd. You'll find it's actually quite monolithic, just not in the sense of all one binary. It's like the Linux kernel being a monolithic kernel -- just because you have kernel modules doesn't change that.

OpenRC can do parallel service activation as well, though it's not based on sockets like systemd. Rather, each initscript declares dependencies on specific services like "Service XYZ must be started before this service may start", or on general classes of services, like "I need a syslog logging daemon before I can start".

Re:launchd

[Arker]

From your link:

"As mentioned, the central responsibility of an init system is to bring up userspace. And a good init system does that fast. Unfortunately, the traditional SysV init system was not particularly fast."

This is the false postulate on which the entire thing is built. This guy thinks that the most important thing about an init system is how quickly it executes, and that is so fundamentally wrong I find myself wondering how the hell the author got himself a job he is clearly completely unqualified for. Does he imagine that all we linux users do with our systems is sit there with a stopwatch rebooting? Was he dropped on his head as a child? Inquiring minds want to know.

The most important things about an init system are that it accomplishes its task correctly, and that the configuration is human readable and easily edited with the most basic tools. The speed of startup is literally the least important thing about it - just one step up from does not matter at all. If you could speed my boot up to the point it was instantaneous, but the cost is a marginally less reliable system, it would be a very poor trade.

On a server your mean time between reboots should be around a year, but on a personal system you might shut down each night and restart in the morning, so let's assume that case, the best possible case for systemd. You will save, what, 5 seconds? Maybe 7 seconds if you are very very lucky. It takes me longer than that to walk to the fridge, get a drink, and walk back to my desk, which time I will be taking whether the system is ready more quickly or not. So it represents literally 0 possible advantage.

Is this really Lennart Poettering's blog? I find the part where he describes the Solaris init quite ironic.

There are other init systems besides sysvinit, Upstart and launchd. Most of them offer little substantial more than Upstart or sysvinit. The most interesting other contender is Solaris SMF, which supports proper dependencies between services. However, in many ways it is overly complex and, let's say, a bit academic with its excessive use of XML and new terminology for known things. It is also closely bound to Solaris specific features such as the contract system.

Just change Solaris to Linux and "in many ways it is overly complex" and "closely bound to Solaris specific features" sounds like an apt description of systemd.

GNU Is Working on It

[Unknown Lamer]

See Daemon Managing Daemon. It was written in the early-00s for the Hurd, languished for the better part of a decade, and has been picked up again. It has a model kind of like systemd, only without the Windows braindamage (I mean come on, ini files as a programming language?). Development on DMD is pretty active now, and it's written in Scheme instead of C so mere mortals can hack on it. The design is pretty interesting, and makes extending things easy. E.g. imagine you run an openafs cell and need a service to grab Kerberos tickets and afs tokens at start. You can just register interest in the service in another service and have it Just Work (tm). From the looks of it, you may even be able to just write a single "Kerberize all the services" service. Better than sysvinit (oh joy, forking an init script) and better than systemd (oh joy, forking an ini-file-pretending-its-not-a-program)..

Re:GNU Is Working on It

depinit

[lkcl]

depinit. written by richard lightman because he too did not trust the overcomplexity of sysv initscripts and wanted parallelism, it was adopted by linux from scratch and seriously considered for adoption in gentoo at the time. richard is extremely reclusive and his web site is now offline: you can get a copy of depinit however using archive.org.

using depinit in 2006 i had a boot to X11 on a 1ghz pentium in 17 seconds, and a shutdown time of under three. depinit has two types of services: one is the "legacy" service (supporting old style /etc/init.d/backgrounddaemon) and the other relied on stdin and stdout redirection. in depinit you can not only chain services together for their dependencies but also chain their *stdin and stout* _and_ stderr together.

that has some very interesting implications. for example: rather than have some stupid system which monitors /var/log/apache2/logfile for security alerts or /var/log/auth.log for sshd attacks, what you do is run sshd or apache2 as a *foreground* service outputting log messages to stderr, chained to a "security analysis" service which then chains to a log file service.

the "security analysis" service could then *immediately* check the output looking for unauthorised logins and *immediately* ban repeat offenders by blocking their IP address, rather than having to either poll the files (with associated delays and/or CPU untilisation) or have some insane complex monitoring of inodes which _still_ has associated delays.

also depinit catches *all* signals - not just a few - and allows services to be activated based on those signals. richard also had a break-in on one system, and they deployed the usual fork-and-continue trick, so he wrote some code which allowed the service-stopping code to up the agressiveness on hunting down and killing child processes. this also turned out to be very useful in cases where services went a bit awry.

basically the list of innovations that richard added to depinit is very very long, in what is actually an extremely small amount of code. i simply haven't the space to list them all, and no, richard was not a fan of network-manager either.

btw you might also want to look at the replacement for /bin/login that richard wrote. it was f****g awesome. basically what he did was use gpg key passphrases as the login credentials.... and ran gpg-agent automatically as part of the *login*. i have never even seen a PAM module which does this trick. it would be awesome to do the same trick for ssh as well.

it's fascinating what someone can get up to when they have the programming skill and the logical reasoning abilities to analyse existing systems that everyone else takes for granted, work out that those sytems are actually not up to scratch and can write their *own* replacements. it's just such a pity that nobody seems to have noticed what he achieved.

what's wrong with systemd

[Rutulian]

First, I have to ask, what is wrong with systemd? It actually works quite well.

That said, even with systemd (and upstart), sysV scripts are supported for backwards compatibility because quite a few system services do not yet have a systemd startup script. I have not looked at the networkmanager or policykit packages, but I am almost certain the dependency is only because of the startup script. If you grab a sysV script, you won't need systemd to install them. This will likely require some voodoo with the package manager, though. My recommendations in order of ease,
    1) use --force to ignore the dependency (this might great problems if you ever have to repair the dpkg database, though)
    2) grab another package from some other distro and install (with alien if need be)
    3) tweak the package yourself to remove the dependency (wouldn't be hard to maintain wrt updates, etc)
    4) compile from source and install (create your own package for maintainability)

Systemd is becoming more and more mainstream on Gentoo, and I suspect that at some point it will take over as the default. However, I doubt support for openrc is going away anytime soon.

I think OpenRC is about as good as a traditional sysvinit/rc implementation is going to get. It is definitely superior to what most distros were using before upstart and systemd came along. However, I don't really see it keeping pace with systemd at this point.

Re:what's wrong with systemd

"First, I have to ask, what is wrong with systemd?"

It's a massive, complicated, and very poorly behaved substitute for a simple, robust, and well behaved program. And it's not just a regular program, it is (if used as intended) a critical system component that will take your entire system down when it goes wrong.

If it were just a bad program, that's no big deal in and of itself, there are plenty, you just avoid them. But these people are not hackers, they have a marketing engine and are aggressively attempting to push themselves into a position where it WILL become impossible to avoid them and still use many new programs.

Not at all. Don't substitute you not understanding a system with complicated and poorly behaved. There are careful design decisions and planning of systemd. You may not agree with them, but that doesn't make it wrong. Systemd is increasingly more popular for a number of very good reasons. It has become a freedesktop.org standard. You could start by reading this,
http://0pointer.de/blog/projec...

But since you probably won't, let me just say this. Serially executing a bunch of arbitrary shell scripts has got to be the worst possible way to design an init system. The fact that it works doesn't make it good. First of all, each script is code. Second, no script is aware of any other scripts presence, although intrinsically linked to and dependent on those other scripts. Third, a typical shell script is >100 lines of block logic to implement the equivalent of "service start". A configuration file for systemd for a single service can often be less than 10 lines and very easy to read.

I know I know, none of that matters, it is too "massive" and "complicated".

Re:what's wrong with systemd

[fgodfrey]

What's wrong with it? Here's my starting list and I'm sure I'll think of more....

- Binary Logs: Sorry, but there is no advantage to not being able to easily look at a log file.
- Failure to Log to the Console: There is nothing more frustrating than watching 5 screens of "Failed, use journalctl to blah, blah, blah..." come by when you know that your root filesystem isn't mounted read/write. There went *ALL* your debug information.
- Failure to Drop to a Shell When It Breaks: If my boot is broken,I want a shell. Not a hang. There's a way to force it to go to a shell, but that's before it does *anything* so you don't get to debug the failure, you get to guess what the failure might be and see if you can debug *that*.
- No way to see WTF it's doing: There's supposedly a command to make it tell you what order (and presumably what'll happen in parallel) things are going to start in. However, if you use that command as root, it tells you not to run it as root. If you do it as a normal user, it doesn't have permission to read all the files to tell you what it's doing.
- Races: I no longer have any idea what order things are starting in. I've had a cluster where everything worked fine. Until the a week and a few reboots later and then it occasionally failed. Don't even start to tell me that "I must have my dependencies wrong". I *KNOW* they're wrong. But I have no tools to help me figure out what "right" is. Plus, have you looked at how many unit files systemd starts on a normal system? I can't hold that much of a graph in my head. With SysV init, unless I turned on some weird parallel mode, everything starts in the same order every time.
- Complexity: I'm not a professional sysadmin. I'm a developer who has to maintain development systems (as well as personal systems) part time. If I worked with systemd every day, I'd probably be able to figure out ways to make it work for me. But I don't. SysV is just shell scripts. I *DO* deal with *those* every day so it's pretty easy to debug.
- Complexity, Part 2: The previous version of init essentially had no bugs. Ok, I'm sure that's not really true but they sure didn't surface very often. Since the results of your Process #1 dumping core are catastrophic (ie, a kernel panic), ideally that process should do as little as possible. That is *CLEARLY* not the design philosophy of systemd. Further, it consumes a decent amount of RAM and the more RAM you consume, the more likely (statistically) you are of hitting a memory error.
- YACL (Yet Another Config Language): Ok, so this is really a minor complaint but I get to learn yet another way of writing config files.
- Filesystems: SysV init tended to mount local filesystems *very* early in boot (some of that broke when udev got involved, but you could usually hack around that) and network filesystems not long after. I'm not entirely sure where systemd mounts filesystems, but it breaks *HORRIBLY* if you move some of the files needed by a service onto a filesystem that's not a "normal" filesystem. I'm sure there's some way to set all the dependencies to make that work, too, but see above, I have no f'ing way of figuring out what should depend on what.

From all outward appearances, the developers have *no* interest in fixing much of any of those complaints. The whole "debug on the kernel command line" fiasco is a pretty clear indication that they "don't play well with others". In the end, I'll see what Slackware has or maybe move (back) to the BSDs.

Re:what's wrong with systemd

[Billly Gates]

So in other words you do not like it because it looks and feels different than what you are used too with old inet.

How is this different than the 50 year old XP users who hate and hop up an down on how bad Windows 7 is because if looks too funny? It is not a bad program.

It is different because event driven is what is needed today. Yes unix users are hardcore and do not like changes to things, but this isn't 1982 anymore where you had maybe 35 shell utils and programs total and you could all neatly manage it all in /etc/init.d like clockwork. Computers did not fall asleep on one network and wake up in another? You did not have to think about usage scenarios where things happened based on a network intrustion or when disk space is near filled. You did not have bloated startup times due to everything trying to load at the same time or things running only sequentially.

Init 3 to run a console, and init 5 for a gui is archaic today, but thought it was cool in 1999. Init itself is very confusing and you needed to be a hacker in the 1980s to understand what was and why. Frankly the only reason it seems so easy to those reading this is because you are familiar with it.

I'm not sure what "keeping pace" means. If openrc does the job, it doesn't need to add features. The issues most people seem to have with systemd is that it keeps adding stuff that is not part of the traditional system init.

Re:what's wrong with systemd

[Arker]

"So in other words you do not like it because it looks and feels different than what you are used too with old inet."

No. Let me be very clear here. I dont like it because it is a bad idea. Nothing this complicated should ever be PID1, for starters.

Init could use a redesign, but a good redesign would look to reduce complexity, not increase it. It would give us something simpler and robust at PID1, not something that's larger and more complicated. And it sure as hell would not be something so complicated, over-reaching, and fragile that it brings your system to a halt when you pass 'debug' to the *kernel.*

Linus has been waaaaay too forgiving of this crap.

"Yes unix users are hardcore and do not like changes to things, but this isn't 1982 anymore where you had maybe 35 shell utils and programs total and you could all neatly manage it all in /etc/init.d like clockwork."

Granted init is over-complicated, the point remains that systemd moves in the wrong direction so this is not an argument in its favor.

That said, if you really cannot manage your init.d with just a tiny bit of effort, your system is clearly over-engineered and needs some simplification. A good design isnt done when there is nothing left to add, it's done when there is nothing left to *remove.* And similarly with a linux install - if you do not understand each and every thing that is happening in your startup sequence then it is time to start pruning it until you do.

Re:what's wrong with systemd

[Rutulian]

Six of your criticisms amount to "I don't know how systemd works or how to configure it." While I understand the frustration, it is not a shortcoming of systemd. If you didn't know how to write a shell script, or how runlevels worked, or how to handle your distributions special way of dependency orchestration, you would be saying the same thing about sysV. Systemd is a new way of doing things. It requires you to learn new things, but it is not as hard as you think. Certainly it is a lot easier to adapt to than some of the other fundamental changes to the userspace that have happened over the years.

- Binary Logs: Sorry, but there is no advantage to not being able to easily look at a log file.

Technically, there is an easy way to look at the logs, it just requires a utility that is not cat or grep. But I get your meaning. Binary logs are certainly not my preference, but for tools that need to interact with and parse the logs, it is a necessity. There are ways to get your text logs back, though, and some distributions configure it this way by default.

- Failure to Log to the Console:

It is in the log. With sysV your were dependent on your particular shell script trapping certain errors and writing them to stdout (or not). With systemd, since the daemon follows the process of forking or attaching to dbus at every step, it collects all the debug information it can and sends it to the log. So "journalctl blah blah" is exactly how you get those messages.

- Failure to Drop to a Shell When It Breaks:

Once again, it is in the log. I'm not sure why being dropped to a busybox shell gives you a much better way to debug than just reading the log messages. If you want to test individual systemd services, you can do that with systemctl start/stop/etc.

However, if you use that command as root, it tells you not to run it as root. If you do it as a normal user, it doesn't have permission to read all the files to tell you what it's doing.

If that is true, it is a bug.

- Races: I no longer have any idea what order things are starting in.

If a dependency issue is causing your boot to randomly fail, then your systemd configuration is horribly broken. That is exactly the problem that systemd is designed to fix. You don't know what order services are starting in because you shouldn't need to. The only thing your unit should do is specify a preferred ordering. That is it. Systemd handles the rest.

SysV is just shell scripts. I *DO* deal with *those* every day so it's pretty easy to debug.

Have you every really had to deal with the complexities of the sysV init system? It is not pretty. "Jiggling the cord" until it works is about all you can reasonably do with sysV when you have a complex init.

I'm not entirely sure where systemd mounts filesystems, but it breaks *HORRIBLY* if you move some of the files needed by a service onto a filesystem that's not a "normal" filesystem.

It doesn't "mount filesystems" at a single time during boot the way sysV does. You can move service files to other filesystems, but then you need to tell the service config that you did this so that it can bring up that filesystem before starting the service. This is actually a lot easier to do with systemd than with sysV.

From all outward appearances, the developers have *no* interest in fixing much of any of those complaints.

Well, this is more of a rant than a series of legitimate complaints. You can't expect the systemd people to understand your issues if you haven't even taken the time to learn how systemd works first.

There are ways to get your text logs back, though, and some distributions configure it this way by default.

...which will almost certainly break if the logs get corrupted at all. The great thing about text logs is that my brain can figure out what values are probably garbage and which ones are the remnants of the (now corrupt) log a lot better than a computer can. There are certainly ways of hardening binary logs, but why? syslog is a PITA to parse by machine not because it's text-only, but because the formatting is from the 1960's. I'm not arguing it has to be syslog format, just text.

- Failure to Log to the Console:

It is in the log.

...until you don't GET the log because it wasn't *WRITTEN*, which probably hasn't happened to you because you're probably booting a fairly standard configuration. But it took me 3 f'ing hours to debug the fact that my permissions were wrong on my NFS server when I was net-booting because I got no shell and no log (because the permissions were wrong). That would've take 20 seconds with logging to the console and knowing more about systemd wouldn't have fixed that.

- Failure to Drop to a Shell When It Breaks:

Once again, it is in the log. I'm not sure why being dropped to a busybox shell gives you a much better way to debug than just reading the log messages. If you want to test individual systemd services, you can do that with systemctl start/stop/etc.

Because sometimes it's a lot nicer to try to reproduce the failure right then and not have to reboot the system in order to get to the log. Remember, no shell means you can't read the log *at all* without rebooting.

However, if you use that command as root, it tells you not to run it as root. If you do it as a normal user, it doesn't have permission to read all the files to tell you what it's doing.

If that is true, it is a bug.

Maybe, but systemd --test --system prints "Don't run test mode as root" on OpenSuSE 12.3 and Fedora 20.... While trying a few other distro's to post this comment, I ran across "systemd-analyze --order --system plot" (which wasn't in the original distro that I was debugging, but it was ARM so maybe it was weird) which appears to be able to generate a graph in SVG, which, while huge, appears to help me a lot.

And sometimes I don't *PREFER* an order, sometimes I *REQUIRE* an order. On my desktop? Couldn't care less because it "Just Works(tm)' and I rarely change the distribution's defaults. On my servers, it's more complex. Maybe "prefer" in this case means it will always honor that?

If a dependency issue is causing your boot to randomly fail, then your systemd configuration is horribly broken. That is exactly the problem that systemd is designed to fix. You don't know what order services are starting in because you shouldn't need to.

If systemd does badly something it is designed to fix ... that does not leave a good impression ;-) On a serious note: never tell me that I don't need to know how things work. If that was true I would be running Windows and people that don't know how things work would not come to me to fix things for them. "XY failed, contact the system administrator" - yeah, I'm the system administrator. So please tell me more than "cross your fingers and try to reboot". I'm the guy that knows how things work. If I can no longer be that guy I become just next useless idiot.

You can move service files to other filesystems, but then you need to tell the service config that you did this so that it can bring up that filesystem before starting the service. This is actually a lot easier to do with systemd than with sysV.

Correct me if I'm wrong, but if all filesystems are mounted early, then it does not matter where you have moved the service. How can it be easier than that?

Re:what's wrong with systemd

[Anonymous Coward]

There is nothing major wrong with systemd, while there are some warts, bugs and misfeatures in it.

This whole thing is just a tempest in a teapot. Just take a look at how heated the discussion about adopting systemd was over at Debian. Namecalling, the-end-is-here postings, lots about the Unix philosophy, promises to never touch Debian again if this or that system was chosen, personal attacks at proponents of the change to systemd/upstart/openrc/sysvinit.

When the technical committee decided to use systemd, the opponents said they were going to have a vote with all the Debian devs about this issue to override the decision for systemd. In the end they did not even manage to get the five supporters that are required by Debian policy to even start such a vote! That basically shows how less than a hand full of people that are shouting loudly are able to give the impression of a controversy, when there actually is none.

Re:what's wrong with systemd

[Ddalex]

You have a pretty good argument about SystemD here, and I want to use it to highlight why I consider systemD especially bad, as software goes.

- It breaks expectations of experienced Unix/Linux users. Where somebody was accustomed to interact with the system a certain way, e.g. having console logging and log files available to cat/grep/etc, systemD changes that. Programs should be designed for human usage - if it breaks already established human interfaces, it drives up the learning curve, and that is bad. We are overstressed with too much information as it is.

- Non-deterministic. If reordering the startup daemons breaks the system, systemD is at fault. You're saying that it's my fault for having broken systemD configuration. I want to remind you that a program should help me out, not raise barriers for me. If I write a configuration, test it, verifies that it works, and then two weeks later it refuses to work, nothing changed, this is horrible design - how was I even supposed to know it will break ? When I test a program, get to run through inputs and verify the results, I don't want unexpected surprises with the program changing behaviour without me telling it to do so.

I'm not going into technical merits here. I am talking as a human interacting with a machine - the behaviour of the systemD-driven machine is horrible.

Would you even drive a car that randomly speeds up a bit before breaking when you hit the breaks, because it thought it would get me a bit faster to my destination ? KISS is a principle because experience shows that simpler things work better.

Re:what's wrong with systemd

[Anonymous Coward]

Yes, it is. The old shell scripts never yanked away system logs, stole core dumps from out of your crashed program, forced system demons to be changed to conform to "the new way of doing things", took over time zone management and reset the hardware clock silently at a whim... those are the true wonders of systemd: mission creep where it doesn't belong.

There was a saying about emacs: "it's a good operating system. Now all we need is a text edtior..."

With systemd it should be "systemd is a nice user space. Now all we need is a good way to boot it..."

Re:what's wrong with systemd

[Anonymous Coward]

What's wrong is that it shits all over the core unix philosophy, where each tool has a specific purpose, is independent of other tools, and is independently replaceable if the need arises. In other words, modularity. Systemd takes that modularity (and the flexibility that comes with it), throws it in the garbage, and replaces it with a huge, monolithic black box. In other words, systemd replaces the unix way with the windows way. That is NOT something I will ever want.

Re:what's wrong with systemd

[Anonymous Coward]

Six of your criticisms amount to "I don't know how systemd works or how to configure it."

Absolutely true, and that's the POINT. Most of us are app developers trying to use Linux to do app stuff, not sysadmins trying to set up a company's worth of machines. I don't normally do plumbing, cabinetry, or car mechanics either... I just use their products all the time. I could learn those skills if I were willing to spend the time and effort to do so and buy the specialized tools, but I'd rather spend my time doing something else. If I'm poking at either plumbing or system level stuff it's because something went wrong and I'm trying to avoid having to hire an expert. The degree to which am able to do so for certain tasks is an indication of how good a job the professional did when they designed the system.

- Races: I no longer have any idea what order things are starting in.

If a dependency issue is causing your boot to randomly fail, then your systemd configuration is horribly broken. That is exactly the problem that systemd is designed to fix. You don't know what order services are starting in because you shouldn't need to. The only thing your unit should do is specify a preferred ordering. That is it. Systemd handles the rest.

We KNOW that our configuration is broken. We wouldn't even be poking at this stuff if it was working. What we don't know is how to fix the configuration. With our knowledge of scripting, sed, awk, and grep we can poke as SysV to at least figure out where the breakage occurs (and, incidentally, we learn about SysV as we are doing so), but if there's too much magic (and if requires tools we don't have, don't know, and can't learn) then we can't figure out how to START (and we can never learn). Heap big magic is fine when it Just Works (tm); but when it breaks we cant tease it apart to fix it again. That's why The Unix Way (tm) is simple tools, doing one thing well, and using plain text to communicate. ANYBODY can read the text files (using text editors, if need be).

SysV is just shell scripts. I *DO* deal with *those* every day so it's pretty easy to debug.

Have you every really had to deal with the complexities of the sysV init system? It is not pretty. "Jiggling the cord" until it works is about all you can reasonably do with sysV when you have a complex init.

The fact is that you CAN get it to work by "jiggling the cord". If there's no equivalent in systemd (i.e. it either all works or it all fails), there's no way to move from "broken" to "fixed". It's the equivalent of a C compiler spitting out "syntax error" and stopping, without telling you what line number (or worse, what file) it was looking at.

From all outward appearances, the developers have *no* interest in fixing much of any of those complaints.

Well, this is more of a rant than a series of legitimate complaints. You can't expect the systemd people to understand your issues if you haven't even taken the time to learn how systemd works first.

And you can't expect users to stop ranting until you take the time to listen to their complaints to learn what their issues are. These complaints ARE legitimate; just because they're complaints YOU won't ever make (because you're the equivalent to a plumber with years of experience) does not invalidate their legitimacy.

The sad thing is that BOTH sides are right. This stuff IS hard and sometimes you just need to hire a plumber (or take your car to a mechanic) to fix the problem. On the other hand, with SysV there were more tasks that were accessible to us and we resent you taking those away from us.

Re:what's wrong with systemd

[Anonymous Coward]

It's a massive, complicated, and very poorly behaved substitute for a simple, robust, and well behaved program. And it's not just a regular program, it is (if used as intended) a critical system component that will take your entire system down when it goes wrong.

Not at all. Don't substitute you not understanding a system with complicated and poorly behaved.

Being difficult to understand is a definition of complicated.

There are careful design decisions and planning of systemd. You may not agree with them, but that doesn't make it wrong.

Systemd is openly trying to do pretty much 'everything' at startup instead of having multiple things that do one thing well working together. I've worked with both systemd-like mono systems and with modular systems. The modular systems are less complicated, period. They are also easier to understand, fix, maintain and extend. Systemd is truly bad by design. And yes, that makes it wrong. That fact that is also critical to the system make it a catastrophe.

Systemd is increasingly more popular for a number of very good reasons.

Systemd is more popular because it is being shoved down peoples throats. It 'more popular' for politically reasons, not technical. Very, very few people would use it if their distributions provided a choice.

It has become a freedesktop.org standard. You could start by reading this, http://0pointer.de/blog/projec...

But since you probably won't, let me just say this. Serially executing a bunch of arbitrary shell scripts has got to be the worst possible way to design an init system.

Yes, parallel processing a bunch of arbitrary scripts is much better. Heavily limiting what those scripts can do is better still.

The fact that it works doesn't make it good. First of all, each script is code. Second, no script is aware of any other scripts presence, although intrinsically linked to and dependent on those other scripts. Third, a typical shell script is >100 lines of block logic to implement the equivalent of "service start". A configuration file for systemd for a single service can often be less than 10 lines and very easy to read.

I know I know, none of that matters, it is too "massive" and "complicated".

Yes, trading bash scripts for a large blob of binary code that interprets another layer of text scripts is much less complicated, If you're just comparing the bash scripts to the large binary blob's scripts.

Re:what's wrong with systemd

[Rutulian]

I'm not arguing it has to be syslog format, just text.

No argument from me there. I don't really understand the rationale of the binary log, so hopefully that will change in the future.

...until you don't GET the log because it wasn't *WRITTEN*,

In these situations you typically redirect the logs to a remote server, something that journald is supposed to be able to do very easily (I've haven't tried to do this yet). But I get your point. The problem with having only the console log, which was the case with most of the init scripts, is that you often don't have a console, or the console output is too long catch the error message. So the permanent log is a better place to put important messages. But I agree it is more convenient to have the console log as well as the permanent log in certain situations. Apparently this can be done with journald. Maybe it's worth a try.
http://log.or.cz/?p=327

Because sometimes it's a lot nicer to try to reproduce the failure right then and not have to reboot the system in order to get to the log.

Agreed. Thankfully this is actually possible with systemd.
http://freedesktop.org/wiki/So...

How easy it is will depend on where the boot process failed, but it is possible to get to an emergency console in nearly every situation without rebooting.

don't *PREFER* an order, sometimes I *REQUIRE* an order.

Yes, you can require an order. But there is a difference between requiring a service (ex: apache requires net and syslog) and requiring an order (ex: net will probably come up first, but apache doesn't strictly require it to). If you do need a specific order, for example a service that requires a network filesystem to be mounted to get its config files, you use the Require combined with the Before or After directives.
http://www.freedesktop.org/sof...

In SysV, almost *nothing* happened before filesystems,

The thing is, not all filesystems can or need to be mounted at the same time, and this is not possible to encode within /etc/fstab. The hack to do this with sysV was to add the _netfs option to your mount to tell the mount command to wait until it thinks the network is up, which only worked maybe 50% of the time. If you think mounting root over nfs is fun, try a service that starts a service that is dependent on the availability of an iscsi target.

I've always hated the "let's make it complicated and blame the user if they can't figure it out" philosophy.

That's the thing, though. It really isn't any more complicated than modprobe.d or pam.d or if-*.d or any of the other config systems that compose a typical modern linux system. It is just new, and will probably require some reading of the docs. But it doesn't take hours. For most, it takes about 10-20 minutes to figure out how to do something you need to do with systemd.

I've gained *no* capability that I didn't already have

I think that's the problem. Too many people have a "works for me" mentality and don't acknowledge the possibly complex needs of other users. Ultimately, linux aspires to be as useful to as many people as possible, not only to the people who have succesfully used it up to now.

Re:what's wrong with systemd

[Rutulian]

If systemd does badly something it is designed to fix

Understand the difference between "doing something badly" and being misconfigured. Nothing can work well if it hasn't been configured properly.

On a serious note: never tell me that I don't need to know how things work.

I didn't say that. You absolutely should know how systemd works. But that doesn't mean you will necessarily know the precise order in which things will start. Systemd has been designed to allow you to specify preferences and requirements, so that you don't have to specify order.

Correct me if I'm wrong, but if all filesystems are mounted early, then it does not matter where you have moved the service. How can it be easier than that?

When you can't mount all filesystems early, this doesn't work.

Re:what's wrong with systemd

[Rutulian]

- It breaks expectations of experienced Unix/Linux users.

I disagree. First of all because there is no reason to disregard something just because it acts a bit differently. Second, it is not as different from standard unix ways as people are determined to think. It is different from sysV, but even sysV was different from other competing systems at the time it was introduced. Not having console logging would be a serious shortcoming if it were true. Thankfully, logging is quite configurable and you can get almost anything you want from journald.

- Non-deterministic.

I would need some more information before I could conclude that it is non-deterministic. The only information I have at this point is "something stopped working." The cause can be any number of things which might be the fault of systemd or might not.

KISS is a principle because experience shows that simpler things work better.

A lot of people have been saying sysV is simpler with pretty much nothing to back it up. Systemd is not that complicated.

just because they're complaints YOU won't ever make (because you're the equivalent to a plumber with years of experience) does not invalidate their legitimacy.

It's funny you say that because I'm not. I'm just a guy who has read the docs and done some googling. To me, systemd is a heck of a lot easier to understand than GNU make.

Systemd is openly trying to do pretty much 'everything' at startup instead of having multiple things that do one thing well working together.

It isn't really. Saying that "Systemd is mounting my filesystem, and bringing up the network, and setting my timezone" is functionally no different than saying "My collection of sysV init scripts are mounting my filesystem, bringing up the network, and setting my timezone."

Yes, trading bash scripts for a large blob of binary code that interprets another layer of text scripts is much less complicated, If you're just comparing the bash scripts to the large binary blob's scripts.

Some excellent sophistry there.

Re:what's wrong with systemd

[BadDreamer]

"First of all, each script is code."

That is a feature, not a bug. I *want* my scripts to be code. That is why they are scripts-

"Second, no script is aware of any other scripts presence"

That is a feature, not a bug. The UNIX way is to do one thing, and do it well. That is how the init scripts should be constructed. Anything else is a failure in design.

"Third, a typical shell script is >100 lines of block logic to implement the equivalent of "service start"."

Which is perfectly fine, as the parameters (if any are needed) are gathered at the top, easy to find and commented. But usually none are needed as they are in the config file for the service.

Thus, these arguments are either neutral or work against systemd. None show systemd to be in any way better. It's a monolithic lump which has no place in a UNIX style system.

Re:what's wrong with systemd

[Rutulian]

I *want* my scripts to be code.

Fine, until you want some basic security in your init process.

The UNIX way is to do one thing, and do it well.

If the scripts didn't need to cooperate to accomplish a task, you might have a point. But they do, which is why sysV init is broken.

Which is perfectly fine, as the parameters (if any are needed) are gathered at the top,

Uh, I don't know how you can think that rewriting the same 100 lines of code to do the same basic thing (but a little differently because everybody writes it differently) in 100 different scripts is a good engineering practice.

It's a monolithic lump

It is not, which you would know if you had bothered to gain even the most basic understanding of what systemd is and how it works.

Re:what's wrong with systemd

[BadDreamer]

I have basic security in my init process, and my init scripts work fine on their own and serialized. I reboot a few times a year, so a few seconds saved on parallelizing that (which is the only time they would need to co-operate) is NOT worth throwing a huge API laden lump into my system.

And systemd is a monolithic lump by design. It's a swathe of API's, which is the Windows way and has nothing to do with the UNIX way. It's an abomination which does not belong.

Re:what's wrong with systemd

[BadDreamer]

To further belabor the point, Debian's argumentation for systemd shows exactly what is wrong with systemd and how it is a monolithic lump of functionality which does not belong together.

https://wiki.debian.org/Debate...

Quote:
"Systemd is not just init. It unifies, in fewer lines of code, everything that is related to starting services and managing session groups: user login, cron jobs, network services (inetd), virtual TTY management"

Just because scope creep and feature creep leads to fewer lines of code does not make it good engineering. On the contrary, mashing together functionality leads to hard to detect bugs, race conditions and needless complexity and interdependence.

And that is precisely the problem with the monolithic and API based approach of systemd. It becomes fragile and version dependent, which is not what init should be.

Re: what's wrong with systemd

[Rutulian]

We've really entered bizarro-land in this discussion now that communicating over dbus has been declared wrong because it is the "Windows-way", whatever that means. Dbus is just IPC, that is all.

How about instead of misinterpreting what somebody said on a discussion forum on an unrelated matter, you read what the actual architect of systemd says.

Myth: systemd is monolithic.

If you build systemd with all configuration options enabled you will build 69 individual binaries. These binaries all serve different tasks, and are neatly separated for a number of reasons. For example, we designed systemd with security in mind, hence most daemons run at minimal privileges (using kernel capabilities, for example) and are responsible for very specific tasks only, to minimize their security surface and impact. Also, systemd parallelizes the boot more than any prior solution. This parallization happens by running more processes in parallel. Thus it is essential that systemd is nicely split up into many binaries and thus processes. In fact, many of these binaries[1] are separated out so nicely, that they are very useful outside of systemd, too.

A package involving 69 individual binaries can hardly be called monolithic. What is different from prior solutions however, is that we ship more components in a single tarball, and maintain them upstream in a single repository with a unified release cycle.

Myth: systemd is not modular.

Not true at all. At compile time you have a number of configure switches to select what you want to build, and what not. And we document how you can select in even more detail what you need, going beyond our configure switches.

This modularity is not totally unlike the one of the Linux kernel, where you can select many features individually at compile time. If the kernel is modular enough for you then systemd should be pretty close, too.

There are more of those here,
http://0pointer.de/blog/projec...

Re: what's wrong with systemd

[BadDreamer]

What makes systemd monolithic is not related to the number of binaries it creates, but that it is API based and contains everything but the kitchen sink. It does not do one thing well; it does a little of everything passably.

And the kernel is an excellent example of what systemd is not; the kernel is not an API based block of functionality. That is the core problem with systemd. It is built like Windows is, not like UNIX and POSIX is.

Your quotes reinforce that fact. It is not an assembly of tools which each do one thing well, but a lump of stuff.

And they can't even keep from bragging about boot speed improvements even in this answer. These guys have a huge ego problem.

Re: what's wrong with systemd

[Arker]

I think you two speak past each other several places.

It's not monolithic in the sense you are using it, it is modular in construction. But it's monolithic in the sense that the collection of modules work together more intimately than they should, and in fact *change* together in ways that quite explicitly discard compatibility. The entire design of not just the init system and PID1 but also of an expanding grab-bag of unrelated system components all get redesigned in ways that are not particularly sane.

It's not about parallel process startup - you can easily do that in the existing system, with OpenRC for instance among many options.

It's certainly not about boot times - I can make a system boot in milliseconds if I need to, that's *easy*.

It's about replacing a stable, mature, and robust standardised modular design with a new design that is vendor-specific and can make and break the rules whenever this is thought necessary to the benefit of corporate strategy.

Which, you know, if RedHat guys really think this is the way to make their stock options rise then more power to them. I think they are wrong, and I think Canonical are just as wrong cause their strategy is the same. I think this path will backfire on them and their forks will collapse in time. But they have every right to try it if they disagree.

But why Debian is falling prey to it? That's the part that sucks.

I've pinned systemd in apt to -1 (so it won't ever install on my machines). So far i didn't have any problem.

Debian isn't the only distribution out there (and that's a good thing - different distros are for different use cases).

What I want is a distro with the huge array of available packages and well-testedness of Debian but using Yum/RPM instead of apt/deb.

CentOS is not an option due to severely limited availability of packages and, no, the third party repos are not an option as they are nowhere near as rigorously tested as Debian before going into the stable release (of course with the CentOS 3rd party repos (epel, rpmforge etc etc) there is no 'stable' release its just a gigantic mess). But Yum/RPM is just a much better package management system than apt/deb.

This distro would also pledge to stick with sysvinit.

I also want this RPM based distro to support in place release upgrades like Debian is unlike the CentOS philosophy of 'reformat and rebuild with the new release).

Why not just improve on whatever the current way is, and evolve it into the perfect init, rather than switch to an entirely new system so often? It annoys current sysadmins who have to learn new software for no good reason, it introduces bugs that make systems less stable, and it further breaks/fragments compatibility between distros.

BSDs and systemd

Don't hold your breath that BSD will adopt systemd. Maybe FreeBSD, but they are basically Linux flavoured BSD anyway. But the _serious_ 4.4BSD based systems just don't see the need, and are happy with the few lines of code that makes up a safe init.

None of the BSDs, not even FreeBSD, will use systemd.

FreeBSD has incorporated NetBSD's rc.d system, and they'll be going with that for the forseeable future:

I have an EFI system and I'm thinking of moving back to LILO. It's not the fault of the boot managers, it's that if I happen to try and boot without the hard-drive plugged in, the motherboard forgets the hard drive from whatever table it's in and it will no longer boot (though the hard-drive itself is detected fine). This is with a fairly modern motherboard. Back to legacy boot until it matures a little, I guess.

Privilege to start a service

[tepples]

(not demand start, but that's very UNIX anyway: in UNIX(tm), things start when they're configured to during boot

For workstations, especially portable ones, shorter boot time is a marketing bullet point that differentiates one system producer from another. So as little should "start [...] during boot" as needed.

or when a USER f***ing starts them.)

But then you have to provide some way for the system to decide which USER is allowed to "f***ing start" each service. Or do you really want to have to wait for a member of the wheel group to show up to enter the command and password to "f***ing start" your machine's network driver? How is that better than letting the network driver demand-start when a program that uses the network is started? Linus Torvalds wrote in this post: "And today Daniela calls me from school, because she can't add the school printer without the admin password. Whoever moron thought that it's "good security" to require the root password for everyday things like this is mentally diseased."

Re:Privilege to start a service

[Cramer]

Sure, point out a thing that's been auto-loading (kernel modules) much longer than systemD has been dreamed of. Network configuration -- even wireless -- has been user configurable by various packages for ages. (Linus' rant aside.) You'd want the network running LONG before any app is started that needs it, or do you enjoy having a 15s delay before chrome can be used; every time you start chrome? (btw, practically everything uses the network these days.)

Linus was referring to the insanity of "security" today. Anything that can add a driver (eg. in windows or macos, adding a printer will add a driver) is an "unsafe" operation -- and rightly so, as too many bits of crap piggyback their way into systems this way. And no, Linus, adding a printer is not "an everyday task." The last time I added a printer was after re-imaging a workstation for a new hire at work. That was 2 months ago.

Re:Privilege to start a service

[sjames]

A few minutes time is all that is needed to come up with an setuid init.d wrapper that can check a text file to see if you are allowed to start/spot a particular service. No need to rip up the whole system for that.

The network can already demand start/stop without dependency hell. It's been available for a few years now in the form of NetworkManager.

This is bullshit. You don't (read: should not have to) add every printer you happen to be standing next to -- which could accumulate to hundreds of printers. There are NUMEROUS technologies to allow printing to locally available printers, through a single system-wide printer. On my previous laptop (granted, that's windows...) I had a single "internet printer" loaded for printing to hotel printers. One system printer, one driver, and I can print to any customer facing printer in any Hilton on the planet. Today, it's called "Cloud Printing".

Re:Privilege to start a service

[fnj]

For workstations, especially portable ones, shorter boot time is a marketing bullet point that differentiates one system producer from another.

Actual "workstations" are never turned off. Therefore elapsed boot time is a complete non issue. Notebooks are another thing entirely. Notebooks are critically wounded computers. Computers with a display that is much too small, a toy keyboard, and a power source that is constantly failing; that has to be watched like a hawk from the moment you turn item on because it runs down like a cheap music box until you wind it up again. OK, they are highly useful, even indispensible, for scenarios when you can't use the real thing, but they should hardly affect the design of an operating system for real computers.

Anyway, notebooks are not so much turned off either as they are suspended or hibernated. Parenthetically that introduces its own set of issues; ones that systemd is arguably very useful in addressing; but that has nothing to do with elapsed boot time.

Finally, elapsed boot time is the LEAST reason to switch to systemd. There are enormously significant ambitious features of systemd that are much more important to a decision whether to use it.

Re:Privilege to start a service

[sylvandb]

And no, Linus, adding a printer is not "an everyday task."

You don't know college. A student is likely to be close to five different printers in a day.

And if you are "close to five different printers in a day" why would you want to add them to your system? There is no need to "add" a printer in order to print to it. The only reason to "add" a printer is if you regularly print to the same one.

Thinking you need to "add" every printer near you is a broken mindset spawned by Windows.

IPv4 DHCP can take from 3 to 15s to setup. And waiting for IPv6 initialization on a network with no IPv6 adds to that. I suppose you've never paid any attention to how long network startup takes from any distro installer -- or during normal boot. If it's not a static configuration, it'll take a real, measurable, annoying amount of time to bring up.

Do you have an android device that turns off the wifi when not "on"? It takes a annoying amount of time for that to setup before any network apps can work. (and then 27 background apps attempt to sync at the same time.)

Re:Privilege to start a service

[tepples]

A few minutes time is all that is needed to come up with an setuid init.d wrapper that can check a text file to see if you are allowed to start/spot a particular service.

In theory, that can be done with sudo too. But a lot of distributions have chosen to go with PolicyKit, and the maintainer of PolicyKit has chosen to go with either systemd or consolekit (which has been declared obsolete in favor of part of systemd).

rc.local

[hierofalcon]

Disable all services possible so systemd doesn't try to do anything with them. In my case, that means basically everything, including the graphical desktop. In rc.local, add in your own service start calls in the approved order from an old Fedora or CentOS version. Generally, even if you use the service blah start command which does the same calls to systemd core functions that the whole systemd launch should be doing on its own, rather than coding the commands directly, I've found that systemd functions start much better from rc.local than whatever zombified magic it tries to do based on its own dependency tree.

Maybe it doesn't matter so much if you're able to use network manager, or are not starting any outside facing services. If you have a complicated network and are still using the network service because NM hasn't been completed yet, then it is really easy to get into loops as it tries to start things that depend on network when it isn't really there yet.

Yes, these are dependency bugs that should be fixed. If I had time, I'd file some bug reports. But most of my bug reports languish till the Fedora release expires and they can expunge them with won't fix, and pessimist that I am, I assume this will be particularly true with the mess that is systemd. Really, they should just be able to enable all available services on their own and see if the system boots. It shouldn't take any of our time writing bug reports at all. Sure they might have to repeat the tests with each different mail server, web server, and the like, but the fix should be about the same for each.

Just doing the ordering basically myself using old standard Linux order for the services that I need to run gets my boots to be reliable and drops the boot times down by minutes (as most things expire after 5 minutes if there is no network otherwise).

Install debootstrap from ports, create ZFS volume, debootstrap onto the volume, configure and start jail. Done. (Works fine on the bare metal, too.)

(Sad to say this since I've been a Debian developer for over a decade, but I doubt I'll be using jessie in any serious capacity except perhaps for kFreeBSD if they don't manage to screw it over as well. I despair at what's happened to the major Linux distributions over the last few years. No longer feels like home, and the years of pushy passive-aggressive behaviour and acrimony which led to it being adopted completely killed my last bit of enthusiasm. I spend all my free time working on Debian.... for this? Giving the BSDs a try for the first time in a long long time, was like a breath of fresh air.)

I spent a month or so trying to get it to use a WPA2 VPN and eventually gave up and went to wicd.

I have never previously heard anyone describe NetworkMangler in any positive terms whatsoever, let alone suggest that it was in some way "friendly".

It annoys current sysadmins who have to learn new software for no good reason, it introduces bugs that make systems less stable, and it further breaks/fragments compatibility between distros.

Because things have changed since the early 1980s. Example lets say you have at work on a network. You close the lid and travel overseas and open it again on the hotels network when it wakes up. How do you write an inet to deal with dynamic changes like this?

Also in the early 80's you only had 25 text based utilities and apps on a unix server. It was not complicated to do things. A modern linux distro has how many apps, daemons, dependencies, etc. Now image the above scenario with a laptop waking up on a different network thinking of all the complexities of a modern distro?

An event driven system makes sense. You can program your system to make changes based on conditions and scenarios that pop up. Network trunk gets hit high? No problem I can setup the event driven systemd to page me and run some packet shaping. Hacking attempt? No problem send an alert and sandbox processes etc.

Sun and Apple have all moved away from inet to event based systems as well.

Some people care about boot times. I'm guessing you're old enough that 2 minutes used to be totally acceptable, and you aren't irritated at what everyone else perceives as long boot times.

Re:Why do distros so often change the way they ini

[Anonymous Coward]

You cannot really make a system that consists of a bunch of shell scripts and have it work for a modern laptop where devices and network connections come and go, and you really want different things to run depending on whether you are at home or on the unencrypted airport wifi.

SysV init needed replacing. It is just unfortunate that the replacement is systemd.

Anyway, I should really stop complaining about systemd, I gave up Linux on the laptop last year and now I am on OS X.

Sure you can. That's what daemons are for, to segregate out smaller functions into smaller single-function processes that are easier to maintain, troubleshoot, replace, etc, rather than one big monolithic "does everything" program. Are you saying that you couldn't have a daemon monitoring the USB bus or SATA bus (getting a signal?) and adding new devices when they appear? Sounds simple enough - maybe needs some USB/SATA bus driver tweaks to make it easier, but I'm not sure why that requires a huge monolithic initd replacement vs. letting a daemon process do it.

Re:aix src

[Anonymous Coward]

And both systemd and launchd are inferior versions of SMF from Solaris.

You say SMF, I say AIX System Resource Controller - Binary log files, configuration in ODM database, etc.

In spite of the headaches SRC sometimes gave, I'd welcome a knock-off on Linux if it were well written.

Easy workaround

[manu0601]

I was using NetBSD, which has no plan to import systemd, I will carry on.

For a server operating system, boot times are meaningless.

Remember Linus' explosion

[PJAJr]

Now wait, didn't Linus himself refuse to let systemd become a kernel dependency? I think the poster has a point. I've used systemd on Arch linux and there's a lot not to like about it and not that much to like about it. I'm a linux newbie as well, so I don't have any particular previous init experience. And doesn't kernel modesetting sort of obviate the need for a complex init?

Re:Remember Linus' explosion

[Arker]

Yes, linus shot that down for now although I would have been happier if he had done it earlier and more strongly. And yes, despite all the fanbois that are absolutely convinced they NEED misfeatures like socket activation, Slackware and Gentoo both have much better systems in place that seem to work just fine as far as I can tell.

Re:"With SysV init, unless I turned on some weird

[gonnagetya]

Bullshit. Sometimes you need to restart servers, and occasionally there's an issue during regular use that will require a restart to clear out. I would argue that servers would have a greater need than most of having rapid boot times to ensure that any unexpected downtime is as short as possible. But I guess I'm the lone voice of reason here.

Condemned.

[AJWM]

As the legendary Henry Spencer said, "Those who do not understand Unix are condemned to reinvent it, poorly."

Clearly the folks behind systemd do not understand Unix.

Re:Condemned.

[Arker]

One of my neighbors awhile back had a sportbike, a 'crotch rocket' as they are called. Or rather, he had all the parts for one. They were usually somewhat disassembled, scattered around the house and front yard. He was constantly working on that thing, swapping parts in and out, and whenever I was willing to listen he would fill my ears with all the details, all the tiny little things he would try, to squeeze another 10th of a second out of some racetrack.

Which, presumably, he actually rode. At some point. In a year I think I saw the bike assembled and him on it twice.

Me, I had a pickup loaded with gear, and I put 50k miles on it that year.

The systemd fans seem to me more than a little like that neighbor - spending months to save seconds.

Where is this boot-time Olympics they are so concerned about, and how much is the prize worth?

Yes there is.

[Anonymous Coward]

Systemd cannot determine when a service is ready for dependent service startups. That requires EVERY service to be modified to tell systemd when it is actually ready to accept service requests.

A simple example is NetworkManager. By default, systemd assumes the network is ready for service as soon as it spawns NetworkManager. Unfortunately, that ignore things like the time it takes for NetworkManager to read its configuration file, initialize network devices... And if you have two or more interfaces, how long it takes for EACH ONE to get initialized.

So what happened? systemd attempted to start httpd - which obviously depends on the network. And it fails.

What was the fix? Modify NetworkManager to send a notification to systemd - which then has "NetworkManager-wait-online" as a target. Mostly works... But if one of the networks NetworkManager requires a DHCP response... NetworkManager itself assumes that the interface is initialized as soon as it starts dhclient... but dhclient may have to wait quite a while to get the information it needs....

So what happens? Another timing failure. How to fix? YET ANOTHER MODIFICATION to a standard service...

So back to apache... If the apache server depends on a database service... how does systemd know if the database service is ready? right - YET ANOTHER MODIFICATION to a standard service, now the database server...

And if something depends on apache?

So what happens if you choose NOT to use systemd.... well, nothing works. All the services depend on systemd now.

Originally, it was planned that Fedora 14 would allow either upstart or systemd... only that failed. Then the plan was for Fedora 15 allow either upstart or systemd. Fedora 15 was released with systemd, and supposedly the option to use upstart... Those of us that tested using upstart were greeted with a nonfunctioning system. And it was impossible to get working.

The next major failure is that systemd depends on dbus and udev. If either of these abort you end up with a nonfunctioning system. On top of that is journald... it too depends on systemd and dbus. If journald dies, errors from systemd/dbus also die... or choke the system into a hang.

And then there are the shutdown hangs. Can't debug them at all.

And STILL people put "sleep" commands into rc.local - as well as filesystem mounts (especially network based filesystems), starts of databases (after all they need the network too), restarts of apache...

All trying to work around a piece of crap that cannot work properly.

I'll grant, a static network is fairly easy to debug (if it is really small). But a complex network can take forever (it is still an NP problem after all). And anytime an error shows up, it usually causes a hang on boot, hang on shutdown, or a non functioning service.

Re:Yes there is.

[sjames]

And yet, it has been working for decades without systemd.

Just poll/wait for the needed conditions when necessary and kindly keep your grubby fingers out of my pie.

Then what happens if I choose something other than systemd? It all just works anyway, that's what. If I wanted dependency hell, I'd install Windows 95 and have fun with DLLs again.

"You cannot really make a system that consists of a bunch of shell scripts and have it work for a modern laptop where devices and network connections come and go, and you really want different things to run depending on whether you are at home or on the unencrypted airport wifi."

Sure you can. Try slackware ffs.

"SysV init needed replacing. It is just unfortunate that the replacement is systemd."

SysV init was a step in the wrong direction, systemd is a giant leap further down that road. But there are plenty of other good init systems. Slackware and Gentoo work just fine without either of them, and so do the BSDs.

Re:"With SysV init, unless I turned on some weird

[Arker]

Bullshit yourself. The ONLY reason a properly configured production linux box being competently administered is going to reboot is a critical kernel patch or hardware failure. Period, end of story.

Of course, if you have installed a bunch of crap designed with the same philosophy as we see in systemd and let it all run however it want, then yeah, you're misconfigured. Doh.

Quit blaming perfectly good tools for your own incompetence.

Re: We'll keep on trucking without systemd garbage

[systemDead]

Keep in mind that *BSD is not alone. There are other GNU/Linux distributions that avoid it. Gentoo are among the distributions working on things like eudev (so you can keep on using udev without systemd).

But besides Gentoo, are there any other major GNU/Linux distros not planning to adopt systemd? From what I've read, Slackware is just holding out until the last minute. Among the BSDs, FreeBSD has the greatest number of packages. The only thing I don't like is the fiendish mascot.

Re:"With SysV init, unless I turned on some weird

[fgodfrey]

Partially guilty. I certainly believe that a 2 minute boot time is acceptable *to me*, but I'm not irritated by people who want fast boot. I'm irritated that their zeal for fast boot resulted in an extremely poorly engineered piece of software that breaks the ability of some of my machines to boot *at all*.

Re:"With SysV init, unless I turned on some weird

[fgodfrey]

What server do you have that makes it through the BIOS so fast that the difference between systemd and SysV is meaningful?

And if your server is so critical that the ~2 minute difference (on a good day) in boot times is a serious business issue, you should really consider running redundant servers anyway since there are a variety of other failures that a fast boot time isn't going to help....

This is a thing on linux in general

[Anonymous Coward]

I have noticed something about linux in general. You know how when you first started using linux, and all the old guys insisted that you call it GNU/Linux, and you thought "yeah, I don't f*ing care?" Well it turns out that they had a point, although it was somewhat obscure. Linux, more than any other unix (well, many of them), leans VERY heavily on it's userland. Try to build Linux without gcc. It's not possible, even though in most areas LLVM/clang is ahead of gcc, gcc is ingrown, and linux depends on nonstandard gcc extensions. There's other examples. Some graphical programs expect an xterm, even though xterm is horribly broken and screwed, because xterm is the standard, so they don't support REAL standards, they support xterm. I think kernel mode setting, though it should actually be a good thing for linux graphics is a fairly major change in X11 which again distances the BSDs. systemd is just the latest and the worst of a long line of insults that linux has been hurling at unix (the idea, not any particular OS).

Now that my whiny little rant is done, I will go ahead and mention the following distros as high quality/minimalist:
slackware
crux

For good ideas on what makes good/bad software check out suckless.org and harmful.cat-v.com (I am in no way affiliated with them, and admit that in many cases they overstate the case. But when you're the minority, you'll ally with anyone.).

In my totally elitist opinion, the problem with software these days is complexity. Anything that you can do to boil software down into a simpler, more logical system is an improvement, if you're not a passive user checking your email and playing flash games.

I am well aware that my opinions are totally unpopular and that most people would rather use systemd as "good enough," or even "better." I don't care if you use systemd, but please do not force your crap on the rest of us. That is not what open source is about. I can and will find a way to circumvent your trash.

EUDEV!

Re:Why do distros so often change the way they ini

[sylvandb]

Billy, three suggestions:

Quit calling it "inet" when you mean "init".

None of what you mention has anything to do with inet or init and so my laptops have done very well in your scenarios using the traditional sysvinit and now with upstart.

If you want to sell systemd, figure out what it does that was not done before, not just what was not done before by init.

Re: We'll keep on trucking without systemd garbage

[Anonymous Coward]

Good point, but the BSD world is becoming far more attractive with the last big distros bending over for systemd. My vote is PC-BSD for its ease of use and practicality. Anything you can do with Debian can probably be achieved on PC-BSD. If Debian had ZFS you'd have a much tougher decision to make.

Re: We'll keep on trucking without systemd garbage

[linuxrocks123]

Where have you read that Slackware is going with systemd? If they do, I may switch to Gentoo. My previous experience with Gentoo was less than positive, but, then, I was using SPARC...

I'm afraid it is indeed too late

[Anonymous Coward]

In Debian testing, dbus depends on systemd libraries. From here, anything any close to dbus _do_ install systemd libraries: cups or kde-runtime are good examples. I do not want to use systemd because I just think they're ****holes (as valid as any other reason, I guess), but I am alreay using libsystemd-logind, libsystemd-journal, libsystemd-daemon0... and I cannot get rid of them without loosing all my environment (and no matter what DE you use, as long as it requires dbus... it requires systemd). I could replace networkmanager with connman as someone else here did, but I cannot replace cups or the productivity on a graphic environment vs a console-based environment.

I completely ignore if this is just a Debian thing, in which case I will leave this distribution after almost 15 years, or on the contrary is a general thing. I simply want one program to do one thing, because if it crashes, only one thing crashes (whereas if systemd crashes you're fucked). I am all "eyes" to read about any 100% systemd free. It is incredibly frustrating.

Remember the Torvalds-Tanenbaum discussion?

[Anonymous Coward]

This discussion sounds awfully familiar. Like the one about the micro kernel in 1992 between Torvalds and Tanenbaum. This is exactly the same but then in user space. Btw still nobody knows if Torvalds was right. Linux grew because it was open source and minix wasn't. And because linux had more features. So we will probably never know about systemd either, unless somebody starts a successful counter development.

Migrate to BSD

[Anonymous Coward]

After being left unimpressed with how systemd has been forced upon us by all the major distros, I've now migrated to FreeBSD and loving it. I don't know why I didn't switch years ago! :-)

The choice of installing stuff via binary packages with "pkg" or building via the extensive "ports" collection is refreshing!

Exactly

[Anonymous Coward]

Swiss army knife system utilities need not apply.

That is exactly what systemd is: a swiss army knife. It's a monolithic solution to 10 different "problems", where all of the "problems" are debatable in the first place. That is the windows way, not the unix way. I pray that at least some linux distributions will take a stand and at least offer choice. If not, then maybe it's time I finally give up on linux and move to BSD. I don't want a black-box startup system any more than I want a black-box configuration system (the windows registry). If you want a windows-like system, then why not just use windows?

Pulse audio has some serious issues...

[bwalzer]

I love PA. I have been using it for network audio since it was called Polypro audio. Having said that, it still isn't finished and maintenance has more or less been abandoned. I recently gave up trying to use it for my media computer. I got tired of living with a 5 year old bug.

I think the problem with Pulseaudio is that it is too monolithic. There is just too much logic stuffed into one place for a good long term open source project. Once the original people lost interest it became too hard to understand for those that just wanted to fix bugs. At this point someone is going to have to devote a significant hunk of their life if the hard bugs are ever to be fixed. Pulseaudio should of stuck to what it did best: network audio...

I'm sure Slackware will switch to systemd - 20 years after switching to PAM.

Personally I'll be more worried about the two minute connection timeout in TCP, when trying to reach slashdot during my vacation on Neptune.

my god a well reasoned argument. well done.

[Anonymous Coward]

^this guy gets it.

and i can concur. there was a thing i, and metric crapton or other people, didnt like about systemd on my distro. (longstoryshort, dhcpd service borkbork) so i fixed it and told the devs my reasoning. and it was patched by the next weekly build. which was cool and stuff.

the simple trick, was being a rational person not stomping in the forum like a primadonna bequeathing salvation in return for them calling me mr smarty mcsmart phd in smartology. someone else would of nailed it sooner or later. and its a nice distro.

Get off of my lawn!

[chuckw]

Every new thing will have a group of people who insist that it is the devil. Maybe it is, and good for them for saying something. Too bad no one is listening to them.

But then again, maybe some people just hate change...

Systemd was built for a reason, maybe a bad one, but a line of thinking went into it. Booting is not a simple thing, despite what you would like to think, and it could be made better.

One thing is for sure though, OSS is not going to stand still, and IMHO, that is a damn good thing...

Re SystemD

[lsatenstein]

It has been tested and retested and liked. If the experts (Linux support and Developers) have no objections, I would go with the flow.

I guess it is like going from a standard shift vehicle, to an automatic transmission vehicle. More convenience but less control. And with sealed motors, no need for feeler guages either.

BSD?

[Anonymous Coward]

YO, its cool and all but the package manager needs a dose on internet connectivity. Its light enough like slackware and all, a bit too light for me.
Assuming this and such awkward command syntax, and that one can get around in vi, you'll fit in just fine. Ive used vi, and Id rather use nano. :P

Hostfiles have their place.

[mmell]

I see you've actually written quite a bit of software, some of it quite good. Too bad you're suffering schizophrenia. Are you this guy? The Start64 malware site shows the following:

But I think he's living at his mother Jan Kowalski's basement at:

Alexander Peter Kowalski

Syracuse, N.Y. 13208

Apartment #1, Lower Level

At least, that's where he wants users of his hostfile manager to send him money.

dependencies?

[Anonymous Coward]

Those dependencies are Debian based.

Systemd does NOT depend on NetworkManager. Archlinux has maintained use of systemd for quite awhile now and do not depend on Networkmanager. They depend on initially, a very basic service to start dhcpdcd. Thats it at most. Anything else is optional.

Systemd is not that bad. It's the distributions that make it so "bundled" not the init system.

I suggest a distribution that respects your freedom more like Arch or Gentoo.

My system boots to the login screen in about 5 seconds with OpenRC since I'm using an SSD for file system caching. I don't need systemd for that.

Re: We'll keep on trucking without systemd garbage

[Arker]

"From what I've read, Slackware is just holding out until the last minute. "

Pure FUD. Slackware does not ship PAM, it does not ship GNOME, it uses EUDEV, if anything it's even less likely than Gentoo to adopt systemd since it's already an option for the tuners that sit there with a stop watch rebooting and compiling all day.

But Slack Gentoo and OpenBSD, at the least, are going to continue doing what they have done so far. Implementing specific features that turn out to be useful enough to start being adopted by useful programs, but individually and without unnecessary breakage to the *nix design.

cat got my tongue

[Anonymous Coward]

I am using Gentoo with KDE and OpenRC and I don't feel any disadvantages. As far as I know Gentoo is not planning to switch to systemd as a default choice. Btw systemd and gnome are available but they are optional.

Re: PolicyKit

[BobbyWang]

It would be very easy to modify PolicyKit to automatically choose between systemd and ConsoleKit at runtime (of course I read the source to draw that conclusion). The reason PolicyKit needs systemd or ConsoleKit, by the way, is simply to find out if a (logged in) user is local and active (the default policy is to only let local active users mount an USB-drive for example). If someone invents another way to find out if a user is local and active, support for that could be added to PolicyKit as well.

Re: PolicyKit

[Anrego]

I'll admit I have not looked at the code, but the problem I would anticipate is needing both as a dependency at compile time, unless it can be dynamically loaded or is all done via external calls.

Re: PolicyKit

[BobbyWang]

ConsoleKit is no compile time dependency (it's interface is DBus and a bunch of files in /var). The systemd library in question (libsystemd-login) would be required even at runtime (but not require systemd to actually run), at least with the current implementation. (Perhaps the library is just a wrapper around a DBus interface, I haven't looked into that.) Another, slightly more complicated, way of doing it would be to have loadable modules for PolicyKit. I would love to see the javascript-part go into a kind add on loadable module since it's adds a lot of overhead and isn't even needed at all in the common case (it's only for "System Administrators [and] Special-purpose Operating Systems / Environments and those audiences only" according to the documentation). But I wouldn't be surprised if PolicyKit gets moved into systemd instead (the way it's written it would be an easy thing do do).
