The CD now boots directly from the ISO 9660 filesystem instead of using MBR partitioning with Minix file systems. This saves some space on the CD and reduces memory requirements by some unknown amount as the root ramdisk is completely eliminated. The x86 hard drive image creation is also rewritten in the same fashion. The setup is modified to be more NetBSD-like (unpacking sets tarballs instead of blindly copying the CD contents). Splitting MINIX into sets is done in another commit due to it being a nightmare to rebase. Since MINIX lacks union mounts for now, a bunch of ramdisks are generated at run-time to make parts of the filesystem writeable for the CD. This solution isn't ideal, but it's enough for an installation CD. Change-Id: Icbd9cca4dafebf7b42c345b107a17679a622d5cd
