* make-initrd.nix: builds a initial RAM disk. The resulting initrd will contain just a Nix store containing the specified lists of packages, with a symlink `/init' to the actual init program in the Nix store. * make-iso9660-image.nix: builds a bootable ISO image. * rescue-system.nix: builds a bootable ISO image (using the two function above) that boots into a very minimal Linux environment containing (at the moment) the dietlibc-based bash and coreutils, loaded from the initrd. Eventually this should become a two-stage boot (load kernel modules from the initrd, mount the actual root file system (e.g., the installation CD), call the real init). The rescue system (probably a misnomer) should become the minimal environment necessary for the installer (on CD) and the boot process of an installed NixOS (on HD). svn path=/nixu/trunk/; revision=6926
