I guess the best description is that a realm is an administrative
domain, similar to an AFS cell, or a Kerberos realm, but for a group of
Coda file servers which share the same volume/user/group databases.

You didn't specify the realm on the clog command line (clog @realm, or
even clog user_at_realm) so it tried to get a default name out of the
/etc/coda/venus.conf file. However that isn't set, I think I set the
debconf priority too low for most people to actually ever see the
question. try 'dpkg-reconfigure coda-client'

Hmm, that is strange. Could you try 'strace -e chdir,open codasrv', the
server should at some point 'chdir("/vice")' and then try to
'open("db/vicetab", O_RDONLY)'. I'm curious what kind of error it got on
either of those.
