I've been mulling and ruminating, and occasionally thinking about
something like this.  What I was looking at (which is only
forward-looking, hackish for backwards) is something along the lines of:
1) on install, copy pristine rc.conf to, say, /var/backups
2) on upgrade, do a diff between that and exiting /etc/rc.conf, to see
local mods
3) perform magical incantation copying over new rc.conf, and
reintegrating changed lines.  Have a -i switch to see and OK the
additions (read: re-merges) to the (new) rc.conf, have it log diffs
between the old backup rc.conf and the new pristine rc.conf, etc.

Now, that doesn't handle the existing systems of course.  But for new...?
Who wants to flame me about it first?
