Init scripts. All this "config manglement" is supporting infrastructure,
not core operations. The init script would do all the initial config
setup into $configdir, and launch master with that config file and a
cyrus.conf as well.

Quite doable. It could probably just use "file" to figure out what sort
of database file was in use. Skiplist is certainly magic-checkable (the
first 20 bytes contain all the details), and I imagine BDB is similar.
I'm _not_ so sure about berkeley-hash vs berkeley-btree, and I am pretty
certain it can't auto-detect berkeley-nosync or skiplist-unsafe!
I'd rather have it detect the wrong type and abort than detect and log
on startup. This is a daemon that deals with files that people care
about, after all!
