hi, not really.  (working on it)  right now, mkfs makes a pretty good
substitute.  it knows enough not to copy older files.  the problem is
not stepping not overwriting running programs.

the straightforward way to do this is boot from cd and use mkfs
to copy from the cd.  you'll have to mount your fs by hand.

the complicated way is to create a ramfs to hide the executables
you're using and hopefully rio won't crash while you're doing this,
but basically  (just an example, i haven't debugged this)

	ramfs
	@{cd /bin; tar c .} | @{cd /tmp; tar x}	# all of it; we have the memory
	path=(/tmp)
	# cd /tmp				# not necessary; mkfs doesn't delete

	cdfs -d $mydev
	9660srv -f /mnt/cd/d000

	mount /srv/boot /n/boot
	# not sure if you want -p; -k is paranoia
	disk/mkfs -bkpvd /n/boot -s /n/d000 <{echo +}
