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 setup is also modified to be more NetBSD-like (unpacking sets tarballs instead of blindly copying the CD contents). This allows massive space savings because only the base system used for installation is stored uncompressed and more modularity (to be exploited at a later time). The sets themselves are to be refined, but are enough for now. Those two steps are melded together because copying the CD contents with isofs as the root filesystem results in some failed tests in minix-posix, probably due to some obscure corner-case bugs in isofs. Having a read-only root filesystem outputs some error messages because it isn't properly supported. Ramdisks on /var and /tmp are used to mitigate this, but the clean solution would involve union mounts, something Minix 3 doesn't support for the time being.
