Subject Proper way to configure Firebird startup on FreeBSD 10

I've successfully installed Firebird on FreeBSD 10 but can't seem to find documentation on the proper way to configure it to run at system startup.

Somewhere on the www, I found that you should add the following line to /etc/rc.conf:


I did this and it seems to work.

I also want SuperServer so I added to the same file:

 firebird_mode = "superserver"

This seems to work too.

What about the default database directory, permissions  etc. What commands are required for this?

Would be glad if an experienced FreeBSD admin could post a reply.TIA.
