Usually FreeBSD ports use different strategy. The service installs
startup script into /usr/local/etc/rc.d, in the case when the service
is expected to be "on" right after installation this script is named
fooservice.sh, but when the service is to be disable by default - the
script is named fooservice.sh.sample. The script should take either
"start" or "stop" argument - the former automatically supplied by
/etc/rc.* during a machine startup, while the latter - during a
shutdown. You can find plenty of examples in the ports tree usable as
a template for such script.
And I don't really think that you need something like `make run'
because it's not much easier than direct call to appropriate script.
Instead you could tweak the port to emit during post-install a message
saying that the user should run `${PREFIX}/etc/rc.d/fooservice start'
if he want to start the service right now.
