Hello,

When shutdown(8) is invoked, the rc.d framework does, in reverse order,
a clean stop of services launched (as declared via rc.conf).

For example for PostgreSQL, I wanted to benefit for such a feature but I
wasn't really enthusiastic about placing scripts in /etc/rc.d (I prefer
to keep things orthogonal between system and local additions, I mean
clearly identifying in the file system hierarchy what is added).

Reading /etc/rc.d/local I discovered that such a hook does exist: it's
/etc/rc.shutdown.local.

IMHO it would be helpful to "advertise" this existence by putting a
template empty /etc/rc.shutdown.local in the base distribution, à la
/etc/rc.local.

Regards,
