I used to set a couple of options (e.g. --replSet) in /etc/default/mongodb to configure the daemon started through my custom sysvinit script (start-stop-daemon ... – $DAEMON_OPTS).

The upstart script sources /etc/default/mongodb, but doesn't actually use any variables. Should I use /etc/mongodb.conf instead?

Ubuntu, Version 2.4.9 (http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu)

Thanks.
