OK, the attached (trivial) patch can be used to create the
miniboot.iso. Its contents is identical to what goes on the
miniinst.iso, except for NOT putting any distributions, docs,
and ports.
The uncompressed size for i386 is 46M, bzip2(1) compressed size
is 16M, which I think many people can afford. (The size of the
miniinst.iso image is 231M.)
Removing *.ko and kernel.debug from /boot/kernel gives 7M of
uncompressed, and 3M of compressed miniboot.iso image. The
patch does not remove them currently, adding one line would
do it. Anyone has a reason why these should not be removed?
One could think that the acpi.ko may be needed for IA64, but
it's already part of the GENERIC kernel.
The numbers for other arches should be identical, according to
these stats:

226 Transfer complete.
Jake, a question for you: can this miniboot.iso image be used on
sparc64 like on Alpha (as Wilko demonstrated) instead of the ugly
boot.flp image? If so, we could remove the floppy creation code
for sparc64 as well.
Cheers,
