floppies as long as they fit, but they are the first to be sacrificed
if space is short, and get moved to a seperate rescue floppy.
This means that the default fdset and the 2.88M image have them,
but others (the "small" and "tiny" floppies) do not.
Sysinst is also back on the "tiny" image, and tested to be working
within 4M.
