When I did a "udebug hostname 7021 -long" to check out the buserver
ubik quorum between the 3 db servers they were confused. Two of
the servers said they were the sync site, the other said it was
a clone. You can specify the db servers as arguments to the
buserver in the BosConfig else it references
/usr/afs/etc/CellServDB. From the server CellServDB man page:
"The server version of the CellServDB file is distinct from the client
version, which resides in the /usr/vice/etc directory on each AFS client
machine. The server version lists only the local cell's database server
machines, whereas the client version lists the database server machines in
every AFS cell that the cell administrator wants the machine's users to be
able to access."
My bigger concern is why the 1.4.2 buserver causes butc to segfault.
