I'm not in favor of keeping this sort of information in environment
variables or in a command-line option.  It should be kept in permanent
storage in the data area.  (In other words, it should be stored in a
file.)  Consider, tomorrow someone wants to move the commit log or wants
to keep duplicate copies of either log.  We should have some extensible
structure in place before we start moving things around.
