I’ve corrected my how-to-install writeup, based on what several people said in dragonfly.kernel. Several steps are now removed, but it still has the same flavor.
According to Matt Dillon, DragonFly will skip the multiple branch style of FreeBSD (STABLE, CURRENT branches) and tag the single main branch, slipping as needed for security fixes.
Aaaand it’s done – rebuilding your system with current sources will give you a uname that reports “DragonFly”. Through some trickery, most ports are apparently not broken by this.
Matt Dillon’s bringing in the ‘DragonFly’ name to replace ‘FreeBSD’ in the source, which may break a number of things over the next few days, including all ports.
Jeroen Ruigrok suggested the Sun Grid Engine (FreeBSD version) as a project for anyone with time on their hands.
Joshua Coombs asked about good books for BSD kernel/network programming. Jeroen Ruigrok listed: “The Design and Implementation of 4.4BSD”, “Unix Internals: The New Frontiers”, and “The Design of the Unix Operating System”.

The make release step no longer depends on perl, thanks to Jeroen Ruigrok.
Yet more __P() macros have been removed. Check the commits record around the 13th to see. __P() should now be gone most everywhere except contrib.
We had some power outages/surges here because of a windstorm, and my UPS didn’t handle it well, along with other local network equipment. So, I’ll be slow with news posts until I get my internal network in better working order.
Matt Dillon noted he would be creating a port override for gcc33, as the port from FreeBSD’s port tree doesn’t seem to work just right.
I’ll quote Matt Dillon’s entry cause I’m working late:
” The MBWTest program (/tmp/mbw1) attempts to figure out the L1 and L2 cache sizes and measures L1, L2, and non-cached linear memory bandwidth.”
Joshua Coombs is kicking around the idea of modeling – or even implementing – his new routing model, in Perl.
This week Matt Dillon is doing:
- lwkt_token and IPI code optimization
- GCC 3.x (just for support of the next item)
- 64 bit AMD64 support
For those of you late to the party and wondering why his work schedule is spotlighted, Matt Dillon is the originator of the DragonFly project, and is doing much heavy lifting.
Jeroen Ruigrok and Matt Dillon wrote up an article for BSDNews.org about DragonFly.
Not directly about DragonFly, but chances are good you are using it. Release 4.4 of XFree86 is due by the end of the month, and you can look at the changelog.
Matt Dillon’s added boot code from FreeBSD 5 – this allows AMD64 and ELF64 support. He also pushed in new linker code and some (not yet enabled) support for UFS2.
Use installkernel and installworld as part of your build process, and you should be fine with these changes. However, you will manually have to copy /usr/src/sys/boot/i386/loader/loader.rc to /boot.
There’s been a lot of new code lately – that’s good!
Jeroen Ruigrok supplied these links about patent issues with Cisco’s VRRP during a thread about importing OpenBSD’s CARP as part of pf.

Variant symlinks are possible now, though you currently have to set the sysctl vfs.varsym_enable. ‘varsym’ can be used to mess with them at any time, however.
