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 +}

Thank you very much, Erik.
I'll try to upgrade this way a test box I should have ... somewhere.
Many days ago you gave me some suggestions about multicast.
On my home network the one-to many communication between 7 boxes works
quite fine.
