DragonFly BSD Digest

Jeroen Ruigrok is setting up Bugzilla for tracking bugs/requests for DragonFly. As part of the process, there’s some 6,000 (!) items brought over from FreeBSD-4. No link yet…

I was pointed at the gmane.org site to find old dragonfly.kernel postings. I moved in what was there, and so the local kernel archive has several months of history added in, now. Docs doesn’t seem to be working yet…

David Rhodus has been commiting a whole bunch of fixes from FreeBSD today. You can tell just by looking at the mailing list archive for commits@, freshly set up, and updated hourly along with the other archives.

Anyone have old list traffic sitting around, perhaps in mbox format? I’d like to backfill.

send-pr, the strange commandline utility for making a bug report, now goes to the bugs mailing list.

Byron Schlemmer put up Matt Dillon’s slides from his Berkley talk as HTML pages.

In a thread about booting media, Matt Dillon noted he was going to:

• Look at Jeff Hsu’s TCP thread code
• implement variant symlinks
• start VFS messaging and environments

VFS will make a number of other things – especially a new port system – possible.

till noted in a comment here that www.dragonflybsd.de is live, and is using the RDF feed from this site.

Matt Dillon explained what he wants the port-creation experience to be for a port maintainer, using VFS, quoted below:

Hiten Pandya mentioned that Robert Watson has set up the FXR website (FreeBSD/Linux Cross Reference) for BSD code. It’s a personal domain, so please don’t tax it at present.

Greg Lehey put up a paper and slides from his Singapore presentation, describing the FreeBSD-5 SMPng work, both in terms of events and code. It’s an interesting read, since this is the path avoided in DragonFly. (Greg Lehey has a 2001 USENIX paper on SMPng, too, which mentions much of the same content.)

Jeroen Ruigrok has fixed make release.

On the freebsd-hackers mailing list, a slight flamewar erupted over discussion of checkpointing code from DragonFly. Amidst the dumbness that normally ensues in a flamewar, there’s some interesting descriptions on what work has been done/will be done on DragonFly. Check out the archive, mostly in the “FreeBSD mail list etiquette” thread. Matt Dillon’s posts here, here, and here are all info-packed.

Matt Dillon’s posted his slides from his talk at UCB Berkley, in OpenOffice format.
