This is good.  It is curious about how this handy interface is documented in
rc.conf but is so hard to find.  Having an example in the man page, as given

would be quite nifty.

This solution works well for me and has the added bonus that it isn't
monolithic like rc.local and is still covered by /etc/security's backups.
