What I want with this derivation is to allow the sheevaplug nixos to build a tarball with all the needed files to boot. Then, this can be unpacked into an SD card, or into a NFS/TFTP server, and then the user can boot the system with help of the uboot console. By now, I have only tried to build the tarball in a PC, in order to develop the nix expressions quicker. There is nothing written specialy for the Sheevaplug in all this, by now. svn path=/nixos/trunk/; revision=20035
