msgcache questions

[Hobbit User]

The msgcache manpage says:


       NOTE: When using msgcache, the BBDISP setting for the clients
should be
       BBDISP=127.0.0.1 instead of pointing at the real Hobbit server.

Are you supposed to do that via the HOBBITSERVERS setting in
/etc/defaults/hobbit-client?  I can't find any doc about setting BBDISP,
but it looks like that's where the hobbit-client init script gets the data
for the BBDISP setting it puts in the runtime config.
