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.
Use this in bootfloppy-big. mkisofs likes to have images fullsize nowadays.
Also, insert a file called "USTAR.volsize.<blocksize_in_octal>" if the
size of the ustar image is not the 1.44M default. This stops bootfloppy-big
from asking for a second diskette.
(Depends on new disktab from etc/etc.i386/.)
Don't descend into bootfloppy and bootfloppy-small since these now overflow,
now do ramdisk, fdset, bootfloppy-big, and bootfloppy-tiny.
