The OpenVPN port does a pretty good job of this. Default rc.d script
is just openvpn. But you can create manual symlinks to it using
openvpn_somename, and it checks rc.conf for openvpn_somename_enable.
Having to manually create the symlink is kind of needed in the openvpn
setup and can lead to left-over files on port removal, but wouldn't be
needed for dhcpd.
Might want to look through the openvpn rc script for ideas.
Yeah, I'm actually kind of embarrassed that I didn't mention that
explicitly, since I was working with openvpn the other day. :) The
script can be simplified with the attached patch. The eval's are a
necessary evil without some other mechanism for setting the defaults.
The patch also removes the default empty variable assignments which are
never necessary or desirable.
