nixpkgs-suyu/fill-disk.sh
Armijn Hemel de289092b2 - various cleanups 
- have mingetty listen on tty2 (but this still fails because of missing /dev/log
- get rid of /init on the targetdrive, solely use /sbin/init (and even that has to go one day)
- use dietlibc statically linked e2fsprogs for the installer. More to come :)
