Depenguinator "Upgrades" Linux to BSD

Posted by CmdrTaco on from the now-thats-just-creapy dept.

cperciva writes "Many systems around the world have been possessed by penguins and dead rats. It would be nice to exorcize these evil spirits, but this can be difficult without physical access to the machines in question. Thanks to a new depenguinator, it is now possible to upgrade Linux systems to run FreeBSD 5.x without requiring anything more than an SSH connection." Clever idea.

      I'm a freebsd user (5.1 - cvsupping to 5.2rc2 at the moment) and I love it. Contrary to some myths, it is great on the desktop. There are some things that just work. Put one line in your kernel config file (devce pcm) and you can just plug any supported sound card in, and it will just work, without the need for any configuration. The same goes with digital cameras: plug it in, and mount_msdosfs /dev/da0s1 /mnt/camera and there you go. Configuration is no more difficult than slackware (in fact, its easier, with automatic dependency checking/resolution ala apt-get, or by simply using the ports system). On the other hand...

      I agree with parent post ... sadly, this announcment will be considered as flamebait. I don't understand this, really. I signed up to bsdforums when switched to BSD, and I must say its one of the friendliest forums I ever been to (including mandrakeusers.org or pclo which are also great). I don't find the hostility against linux in bsd users there the way I find hostility towards bsd users from linux users here on slashdot or recently, even osnews.In fact, there is a linux section (other os) on bsdforums, and I saw people helping out with fedora install or whatnot there without any 'use bsd instead' notes. I wish this continual flamewar would end, but frankly, I believe (mod me down if you wish) that most hostility comes from linux users. If you find some bsd folks here a little touchy, considering the amount of trolling every bsd announcment gets, it is a small miracle that people still come here for bsd news, that they are not as bitter as one would expect (but than, they - warning, flamebait! - seems to be more mature.

      This is not because BSD is better or something. I like linux as much as I do BSD, I just like to use the latter better, because it is more interesting/fun to _ME_. I believe the linux crowd can be (and maybe it is) as 'mature' as bsd folks, but it is a more diverse group as well as considerably larger, so I think there is more room for a small but vocal minority to ruin the relationship and raise ill will towards each other. I wish that more considerate linux users would help out modding down trolls, afterall, we both have profited from each other's work.

      Unfortunately, due to licencing, code exchange is mostly a one way road (BSD > Linux), but still BSD has to thank for GCC (well, not specifically linux) or the ULE scheduler (which is partly based on a linux developer's work - more linux specific) without which our beloved OS would be poorer.

      Anyhow, the point I was trying to make is that this article can sadly be considered a flamebait, although we see similar announcment without anyone fearing that it is on the 'other' side. It would be nice to live without fears that such announcments would attract a large amount of trolling, to think that the article (read it!) has its on technical merits that can be interesting to anyone who visits slashdot (nerds?) no matter what OS they use.

      Around '97 I was becoming interested in Unix/like systems. So I got myself an old 486 and was trying to decide to load it up with - FreeBSD or Linux. I was coming from a very Windows-centric viewpoint, so I asked around for advice. One friend suggested Linux (Slackware to be exact). Then I went to chat up the folks at the ISP I had a part-time helldesk job.

      The ISP in question was almost an entirely BSD shop. They were great believers in FreeBSD and, of course, suggested it. When I asked them about Linux I almost got my ear chewed off - and not with helpful reasons why to pick one over the other. I was shocked at how much animosity they had for the system.

      I can understand animosity towards Windows and Microsoft. I have shared some of the experiences that build up that contempt. But I can't understand why there is this friction between BSD and Linux users. Maybe its the old "Ford vs. Chevy" thing. Or maybe I just haven't experienced things as a BSD fan.

      You're approaching FreeBSD from the wrong direction. At the risk of over-generalizing, the problem is that Windows, Linux and FreeBSD people approach problems in three different ways.

      Windows people want to know "what". What do I do to use a digital camera? What are the exact steps I need to take to make a picture I just took with my camera be my desktop wallpaper? And don't leave out any trivial steps, or I'll get confused. A good example is my mom. She doesn't know how to use Internet Explorer if it isn't running in a maximized Window. And even though she knows how to save a document she wrote, she doesn't know how to save a document someone sent to her in the mail. Although my mom is an extreme example of Windows users, I've seen similar attitudes amount highly experience Windows developers and administrators.

      Then there's the Linux approach. It's focused on the "how". Witness all the HOWTO's polluting the documentation space. While a much better approach, it's still limiting. The Windows user is stuck with eating out at restaurants and ordering take out food, but the Linux user has a recipe book, so they can cook their own food. But if there's a recipe they want that's not in the recipe book, they're still stuck. That's your problem. You're searching the Linux recipe book (newsgroup after newsgroup) for a recipe on how to use digital cameras.

      The FreeBSD (and traditional UNIX) approach is "why". Why do we do what we do when we mount a filesystem? When we know that, then we know how to use a digital camera. Because it's the same damned thing. We don't need a recipe book with ten thousand recipes for ten thousand different kinds of bread. All we need is a primer on baking bread. The rest we can figure out.

      Notice your use of the phrase "sure, that's an easy command, once you find it". You're looking for a specific recipe. A specific HOWTO. A FreeBSD user would say "that's an easy command, once you know why." The "why" is that a digital camera is a filesystem. So you mount it just like any other filesystem. If you don't want to type in the resulting command each time you use the camera, then do the same thing you do with all your other automounted filesystems, use an automounter! It's no different.

    This is no troll, it's a fact, and extremely hard to dispute ("Linux never crashed for me" does not count).

    My experiences with FreeBSD have been universally bad.

    From the fact that it didn't support the built-in network card on my laptop (worked fine in Linux and Windows) to the fact that no less than 3 versions of the FreeBSD boot CD *and* floppy hard-locked on my desktop on install (worked fine in Linux and Windows). Then there's the fact that the POSIX threading support was bad enough to make our core application unusable on all versions of FreeBSD (up to 4.9, and it works fine on Linux and Solaris).

    I also find the whole CURRENT/STABLE/RELEASE naming a little confusing, but I could live with that if FreeBSD actually provided any real-world benefit. The only areas where I've seen a real, measurable benefit to FreeBSD is in high-volume UDP servers (which is to say: DNS, or possibly NFS) or the IPv6 stack (thanks to the KAME project).

    The fact is the FreeBSD technology is playing catch-up to Linux, and even if the technology were great, the childish "my OS is better than your OS" attitude of most FreeBSD users that I've met is what really makes FreeBSD stand out.
