Back from holidays...

It would be nice if we could find a consensus what should be done with
my patch in D451. The code itself works fine for me, but what's still
unclear is what config files should be touched by it:

1 /etc/rc.conf
2 /etc/rc.conf.local
3 /etc/rc.conf.d/$servicename

I could add some flags to service(8), e.g. -l to edit rc.conf.local, -d
for /etc/rc.conf.d.

But please don't let the review rot any longer. :)
