The rc.d style ports scripts' behaviour diverge from that of base system
rc.d scripts. The main culprit is not enough communication among rc.d
developers and ports developers. That does not mean that we should change
the relatively stable/expected behaviour of rc.d to accomodate ports rc.d
behaviour which is still in a relative state of flux.
I'll bring this up with re, and portmgr, and see what they have to say.

It's not as simple as that. Besides the security implications there are also
many possible corner cases. To name just a couple: diskless, / (root partition),
/usr/local, /usr/X11R6 on different partitions or even mounted remotely, etc...
How is rc(8) going to handle all these possible scenarios. It's possible,
but it's not trivial. And this close to 5-STABLE is not the time to start
experimenting with it. If you feel otherwise, then separate this particular
issue out from your patch and post to -arch.
P.S. - STOP TRIMMING FREEBSD-RC OUT OF THE CC LIST!
