A simple explanation wrt AstLinux, unionfs is a read/write filesystem overly to a read/only filesystem, The 'union' of the two creates one unified read/write filesystem seeded with the read/only filesystem. As far for the keydisk, it can be a separate ext2 partition, separate from the unionfs partition; but the /mnt/kd/ directory can also be handled by the unionfs overlay. In this latter case astkd= is not defined and asturw=/dev/... is defined. There has been a lot of discussions of this a few months back in the archives.
