I have created slides for an introduction to DragonflyBSD which was originally used for a recent get together of the Philippines BSD users group.Content was mostly my understanding of DragonFly which was luckily quite accurate. But after some suggestions and comments from the DragonFlyBSD community, I have revised it to be more accurate and informative.
Thanks to Matt Dillon, Joerg Sonnenberger, Jeff Hsu and the DragonFlyBSD community. Thanks also to Robert Watson for a very brief but nice explanation on the threading.
The slides can be seen here http://kerneltrap.org/files/xedx/dfly.pdf 133337 bytes.
And you didn’t fiddle with the filesize?
DragonFly looks really interesting, I might test it on one the machines here.
Saw the differences however i missed the reasons of why i should run Dragonfly over FreeBSD or NetBSD.
DragonFlyBSD _currently_ doesn’t offer any advantages over FreeBSD or NetBSD.
There is a large amount of work being done to the base subsystems to make it much easier to manage the codebase, and add new and interesting functionality.
The DragonFlyBSD is looking at doing things that aren’t typically done in systems today due to complexity or just plain laziness. It’s kind of like a running research paper.
The journaling layer that Matthew Dillon has been working on has some really neat applications. This doesn’t just apply to filesystem journaling, which it can be used for, but for the system as a whole, such as backups and process streams.
The possablilty of an SSI system is really the big thing for me. Having a cluster (slab) of computers act as a single entity (ala SGI) is a _REALLY_ neat aspect of some of the work they are currently planning to accomplish. Check out the Kernel and Commit forums available from http://www.dragonflybsd.com or use CVS to check out the sources.
You know, it’s very surprising that dragonflyBSD articles don’t get more comments here. This project is pure fun as it really is like a big research project as Subatomic Toad suggested.
I get the feeling that the community here is now less interested in the technical side of things and more interested in politics. *sigh*

Its a world of technical advantage, cost effectiveness and ROI. I am a technologist tasked with employing the best technology available for the purpose of running a business effectively. I care less for the personal masturbation works or ego trip distros.

VERY well said. Unfortunately alot of people who post here don’t understand it or don’t even need too. The majority seem to be tinkerers compared to somone being asked to implement something a business can depend on. Not saying either viewpoint is better, just that we need to be able to know who this board caters to when reading the news and the subsequent comments.
On that note. I LOVE DragonFLY. My favorite of all the FOSS’s. I love the philosophy along with the OS which has given me no problems since it has been marked stable. I sadly retired all my Slack boxes (was my favorite for 5+ years) and I even have a college running DFBSD for their in-house webserver/perl forums.
eE
But 90% of the comments here have nothing to do with choosing good technology for business. Neither do they have much to do with technology. Also, this site is really really not business oriented at all. If it were it would not post many of the stories it does.
Not trying to be negative, but if you really wanted to understand the technology you use you would be interested in projects like this. Not because dragonfly is immediatly useful, but because it will eventually give you valuable information about what sort of technologies works well in different settings.
Lastly, please don’t try to sound all holy and smarter than the rest of us. Calling research ‘personal masturbation’ is insulting, rude, and very narrow minded. I’m sure many of us have technology jobs and are very good at them. That does not mean that ‘work’ is all we think about 24 hours a day.
I run OpenBSD, FreeBSD, OS X, and Windows NT (5.x) machines, and the operating system I’m most interested in is easily DragonFly BSD. A lot of the design philosophy is very appealing to me, and Matt Dillon’s goals seem both reasonable and erstwhile. It’s just that DragonFly BSD isn’t that far along yet.
Anyone on here use this regularly? I use OpenBSD for a firewall, but was thinking about trying FreeBSD or DragonFly on a desktop again (used Free about 3 years ago). Before trying I’d be curious to hear opinions on DragonFly. If anyone is really into it, I’d suggest submitting a review and seeing if OSNews would post it…

What the hell does this have to do with an open source BSD operating system? If your only concern is implementing technology to maximize ROI for business, then stick with NT, Linux, Solaris, etc.
Most of the open source or hobbyist operating systems reviewed and discussed on this website will probably never have wide-spread adoption. But that generally isn’t the point and may actually hurt the effort in the long-term. Removing market and competitive pressure allows these developers to scratch their creative and intellectual itches. In the end it may result in absolutely nothing, or they may actually discover better ways of doing things. Maybe that would result in wide-spread adoption of their OS, or just wide-spread adoption of their ideas into existing operating systems. An ego trip can also be the impetus for great ideas.
The DragonFly homepage says they have imported the new rc.d system from NetBSD (like FreeBSD, they call it rcNG).
But is it FULLY integrated (like, obviously, in NetBSD), or do they use a mix of the old and the new system (like FreeBSD) ?

Well put. There are many examples of this.

I don’t take the DragonFly project seriously. The DF mailinglists is a real playground, filled with Matt’s minions, constantly bashing everything that’s related to FreeBSD. Take that David Rhodus guy for example, he seems to have dedicated his life to bash FreeBSD. Not very impressing.
They have som bright guys, like Sonnenberger and Okumoto, who also is very friendly towards FreeBSD, but is that enough?
I didn’t realize that there was that much bad blood between the two projects. From what I’ve read, I got the impression that the FreeBSD and DflyBSD projects were pretty friendly. I remember reading interviews with Matt Dillon and he was very positive about FreeBSD saying just that he and them have different veiws on the direction the project should go, hence the split.
Of course, I don’t read the mailing lists, and don’t doubt your experience. It is unfortunate when people let their emotions get the better of them. But if you look past that sort of thing, the dfly project is very interesting.
Most of the friction between the two projects is purely ‘percieved’ and mostly fictional. It’s caused by rumours and BS posts in forums. Yeah, there’s been the occasional venting of steam but you’ll see that on _any_ project’s mailing list.
I think everybody ought to stop making mountains out of mole hills and focus on the technical merits of the project.
Very well done summary
I didn’t realize that there was that much bad blood between the two projects.
It’s not as bad as Behemoth makes it out to be. Yes, there are some childish people on both sides. However the DF mailinglists are certainly a lot more than a “playground” for FreeBSD bashers. DF developers are making real progress towards their stated goals. Which means someone must be doing something other than typing “FreeBSD sucks!” ten times a day, not to mention the fact that some DF developers also develop for FreeBSD. Judge DF and FreeBSD on their merits not on what a few people with a bone to pick say about either project.
DragonFly has David Rhodus and FreeBSD has Dag-Erling Smørgrav. Every project has its set of controversial people.
Thanks Brett (IP: —.nrlssc.navy.mil) and everyone
btw after two further revisions I still managed to retain its filesize (133337)
DragonFlyBSD Slides? Come on, you don’t write headlines like that. Sounds like a cynical article from The Register.
