nixpkgs/lib/make-system-tarball.sh
Lluís Batlle i Rossell 1dd3162d7c First attempt at trying to get a tarball of a bootable nixos system.
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.
