Hi again,

The root volume is just like any other volume, it's only difference is
that it's name is stored in /vice/db/ROOTVOLUME, and a client has a nice
RPC call which it can use to ask a server for the contents of that file.

So to create a replicated rootvolume, create a replicated volume, and
stick the name in /vice/db/ROOTVOLUME (on the SCM, it should then be
automatically propagated to all other servers).

Oh, by the way, you'll confuse the hell out of the clients until they
have been reinitialized (the -init flag does the trick, or create an
empty /usr/coda/venus.cache/INIT file before restarting).
