* nix-0.10pre5896-paths.patch :: this path adds coreutils to the searchpath,
so nix-prefetch-url can find "basename"
* nix-0.10pre5896-chroot-once.patch :: unsets NIX_ROOT in various scripts,
to prevent that when NIX_ROOT is set and one of the nix tools is called that
chroot() is performed once more
