Eelco Dolstra ce250ffb37 * Installation CD: include a lot of modules (SATA, PATA, Firewire,
USB, some SCSI controllers) in the initrd for mounting the CD.
* Add nix-hardware-scan to the system.
* Upstart: don't use the -v flag.
* Include the NixOS version in the ISO image filename.
* Include testdisk and ms-sys in the CD.
* Some bugfixes in the installer.
