Found the answer to my own question. I just need to add a partition-<name>
definition to imapd.conf and restart the daemons.  (I HUP is insufficient, 
unless you are willing to wait for all the imapd's to restart on their own.)

The mailboxed.db contains the partition name, which is "default" by default,
in our case.
