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.
