By reading the source, I determined that the mupdate master maintains
the same mailboxes database that's used for local mailboxes. That's
why it can't be run on a unified server or on a backend server.
Giving the mupdate master its own mailboxes database would solve this
problem. In that case, each unified or frontend server would require
a mupdate slave to synchronize its mailboxes file to the master copy.

By reading the source, I determined that only the mupdate slave is
able to synchronize a local mailboxes database with the master copy.
So, I moved the mupdate master to the backend server, again running it
under a separate instance of Cyrus master, with its own imapd.conf
file. Now everything works. The mailboxes database on the unified
server now contains both local and remote mailboxes.
