DragonFly BSD Announces 1.0RC1

CoolVibe writes "Matt Dillon announced the availability of DragonFly BSD's 1.0 Release Candidate #1. Get it at Dragonfly BSD's site (please use a mirror or post mirrors as comments). Changes and features include: variant symbolic links, UDF support, lightweight kernel threads, message passing, GCC 3.4 in the tree, binutils 2.14, Kernighan's awk 2004-02-07, BIND 9.2.4 rc4, CVS 1.12.8, libpcap 0.8.3, tcpdump 3.8.3, less 381, MMX/XMM kernel optimizations are now on by default, greatly improving bcopy/bzero/copyin/copyout performance for large (>4K) buffers, XIO, acpica5, new AC'97 codec support, network stack revamping, long standing bug fixes for wide variety of support and stability issues, and way, way, way more. A new installer is also in the works that uses DragonFly's new CAPS IPC mechanism. The installer beta is available from LiveBSD. (Not updated to RC1 just yet, but it gives a nice idea of the progess made)"

Exciting stuff

[Dan Ost]

I think this project is a good model for how large projects should be handled.
They published their design and a roadmap for implementing their design. This
makes it easier for a lurker who is watching the project to actually jump in
and contribute to it.

At least, it seems that way in theory. Anyone have any idea how responsive the
community has been to this project?

Uh, anyone want to give an idiot like me a concise and clear reason why DragonFly BSD is superior to the other BSD variants? What specific applications is it more suited towards?

No, I'm not trolling, but thanks for asking.

Not only did you not read anything in the links in the /. post, you appear to have not even read the post. Go do this. In short, we're about performance.

Secondly, you appear to be looking for a reason that we are ``superior'' to any other BSD variant. When you find clear reasons why one operating system is superior over another for any given application, please let me know.

And, as stated BEFORE I said that, there's a clear and concise list at dragonflybsd.org. What more do you want?

I actually did read the features that were listed in the article, but many of them were over my head.

Like I said, treat me like an idiot. Kind of like if I were to go to an auto dealer, talking to me about pistons, catalytic converters, and the like would be of no help. I'd want to know about fuel efficiency, overall emissions, power when going up hills, how much you could fit in the trunk and the back seats, and its overall safety record.

So, in operating system terms, I'd want to know things like: this operating system is designed for highly secure environments, or environments where speed and system response is most crucial, or where stability is exceedingly important, or where you deal with extremely large file sizes. Would using this OS for a web server or firewall be overkill? Is the system designed to be easy to maintain -- it did look like it has a package system that they're going to make similar to Debian's, and that would be a nice feature.

I don't know hardly *anything* about SuSE or Debian, but if I were asked, I'd respond, "Well, I know that Debian has extremely easy-to-use package management. A great number of people swear by Debian as being extremely easy to install. Other people say it's slower. SuSE comes out of Germany, so it's especially popular there as a lot of the documentation is available in German. However, if you don't know German it may be difficult to find support, as it's possible a lot of the forums will be in German rather than English." If they were interested in specifics, I'd then say, "I'm sorry, I don't know enough. Check out Google for reviews/benchmarks."

People raise "SuSE vs. Debian" type questions all the time -- it's a normal question, and it's often much easier to read responses that have been distilled from personal experience than poring through each distribution's website. I *did* go to the DragonFly website, read through the intro, but didn't understand it fully -- it was definitely written for people very familiar with BSD, and with the apparent misguided path of FreeBSD-5. I also read the FAQ. I didn't realize that I should check out the "Goals" section in order to realize what DragonFly offered differently, and then again "iomodel" is not necessarily the most appealing link name for a noob luser like myself.

Since this is one of the early appearances of DragonFly BSD, I think asking for a general explanation of what makes it so damn special is not out of the question.

So bleeding edge development, perhaps? I was pretty unawares of what DBSD was all about, although, to be fair, I didn't follow it. I think this is a good idea to breathe some new life into the BSDs...I'm sure successful features from DBSD will be borrowed by the others once they prove themselves useful and stable. Maybe even ease the linux troll's complaints about how slow development is in the BSD world.

There is a huge difference in developer support, which is the main reason that FreeBSD is the only fork that has reasonably modern performance features.

Sorry, but that's bullshit. With people like Poul-Henning Kamp nuking stuff they don't consider useful (see the recent ibcs/sysv compat thread on freebsd-current) and doing damage to the team work others have put so much effort on, I see more and more people migrating to NetBSD (alpha support is almost EOL'd for FreeBSD too) and DragonFlyBSD.

NetBSD's scheduler activations already outperform FreeBSD's KSE, and work on most architectures (as opposed to FreeBSD's x86-only KSE)

Sorry, but NetBSD is already ahead of the game, sans the flamers like Poul-Henning and David O'Brien.

Linux doesn't do any of those, since it's just a kernel. Some distros might hack in something like PAX, but its nowhere near as pervasive and as well tested as on OpenBSD - it takes toolchain support for randomised shared libraries, and OpenBSD also fixed a lot of bugs in Propolice while integrating it, showing noone else has seriously tried it to use it before across multiple architectures.

Oh I didn't even mention stuff like StackGhost on sparc...
