Changing data_directory on a running system would be fine; there
is nothing that "postfix reload" can't fix, and all you lose is
some non-essential state. However it would make sense to warn
about queue_directory changes (and perhaps config_directory).
The master(8) does not use a lot of parameters because it was
written before main.cf support was implemented by May 1997, so it
is not like there is a lot to warn about.
It's not clear if mail_conf.c is the right place to fix this,
though. I'll look into this today.
