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
