a kernel panic. initrd should be brought back to a few megabytes instead so it can be safely unzipped in memory. Ideas: - klibc instead of glibc - leave out a lot of packages in the initrd: - gcc - linux-headers - ... - have a minimal "stage 1", which mounts the CD (figure out how) and remounts part of the CD on /nix and /nixpkgs svn path=/nixu/trunk/; revision=3502
