MFS root FLOPPY we don't want.  MFS root FILE SYSTEM we need,
and it is still generated by release.9 and used in the CD-ROM
installation.  Its size is another subject.

Not quite.  It's a r/w root file system (MFS), without a
kernel and distributions.

No we don't.  For the CD-ROM installation (with the help of
/boot/cdboot), the GENERIC kernel is used.  I think some
people working in this area (including you) were confused
about this for some time.  If you don't trust me, ask JHB,
or just boot off the 5.[01]-CD/DVD and watch the ident
string.

That's what my patch does.  Not defining the corresponding
*SIZE, *INODE, and *LABEL constants does the trick.  The
NO_FLOPPIES knob is not strictly necessary -- if you look
over the conditionals in the release.10 target, you'll notice
that with these changes, the release.10 will be a no-op even
if we don't enforce the NO_FLOPPIES for amd64 and alpha.
The purpose of enforcing NO_FLOPPIES is to avoid unnecessary
IFs in the release.9, ftp.1, and cdrom.1 targets.
