Debian GNU/kFreeBSD
29th December 2010

So when I was travveling to my parent's for christmas it looked like I'd have limited computer access. My Netbook is quite OK for reading mail but not really useable for any real hacking. And my trusty Thinkpad (Z61m) was oopsing when X was running so not much useable either. But as some Live CDs placed here were working well I decided that this would be fixed by an reinstall. And as I was reinstalling anyway I decided I could just choose kfreebsd-amd64. Turned out to be a quite entertaining decision with lots of stuff to hack away with

wireless

Bad news: there's no wireless support on Debian GNU/kFreeBSD at the moment. This problem is tracked as Bug #601803 so for wireless internet you will need a (plain) Freebsd chroot. Haven't tried this myself yet -- busy figuring other stuff out.

SBCL

Having a FreeBSD chroot I decided to give SBCL on GNU/kFreeBSD another try after having failed to get it working in a VM some time ago. With quite some help on SBCL's IRC channel I managed to build a patch that enables building (you need to force a :os-provides-dlopen to the feature list additionally).

There's currently no multi-threading working so I hae a project for the rest of the hoidays (well lots of other stuff to do as well ;))

Audio

Some more user-related stuff now. As it is this time of the year I wanted to listen to some 27c3 streams so I needed working audio. However there's no OSS device available. Turned out you just need to kldload the right module (here snd_hda) to get sound working.

Volume was rather low although hardware controls of the soundcard where at max. As that's all OSS there's no point looking for alsamixer. Turns out aumix can do that here.

IPv6 aiccu stuff

Installing aiccu, copying the config in and starting did not work out as well. I already tried to do that from within the FreeBSD chroot already (which doesn't work for some reason) until I discovered just loading the if_tun kernel module solves the aiccu on Debian issue quite well. To get a default route up the last step was finding /lib/freebsd/route again -- /sbin/route is a wrapper around that abstracting differences in BSD route but not supporting IPv6.
