It's really not that difficult.

Yes it is. It's documented that run_rc_command supports
"start/stop/restart/status" by default, along with any others given
to run_rc_command. That will be documented in rc(8), along with other
details of the system.

We've been relying upon rc.subr for other functions (checkyesno,
mountcriticalfs, etc) it provides to our rc system for over two years
now. I just don't buy this argument. That's like saying we shouldn't
have C libraries.
Speaking as someone whose actually written a lot of traditional
style `do everything in the script' approach, and converted them
to using run_rc_command, the overhead in using the latter is much
less. mrg's original work was a bunch of stand-alone scripts, and
adding or changing functionality was much more difficult in that
environment than using run_rc_command.
Darren, you appear to be arguing against run_rc_command based on
spurious hand-waving, rather than speaking as someone whose sat down,
written the scripts, and compared the benefits of both. I.e, `put up
or shut up'.
