The answer:
<slaps head> I spent so much time looking at the rc scripts that I neglected
to look at the /usr/sbin/shutdown program, which is itself a shell script.
I can just pull the rwall stuff out of there. Several people mentioned that
doing an "init" does the is the shutdown without the wall; I haven't toyed with
that so I am not sure. Old habits die hard and I'm used to doing a shutdown.
One person said to just do an /etc/reboot or /etc/halt and that will run the
shutdown scripts. No they don't! Running /etc/reboot or /etc/halt does
NOT run the shutdown scripts /etc/rc?.d/K*. Several people said to just
disable wall in inet. The problem here is that shutdown would still be
trying to rwall-- much better to cancel it at the source IMHO.
