from lots of man pages, and old POSIX docs, they say that to 'reboot' or
stop a unix system you send a SIGTERM to everything.
the 'critcal' systems that need to stay up during reboot/haltsys (init!,
getty) or anything that needs to do cleanup are supposed to trap (and
ignore SIGTERM)
once the non critical systems are stopped, THEN you send the SIGQUIT.
I can't see anything critical about cron running during a reboot or
haltsys. SIGQUIT should be the default for it anyway.
did you verify that this works for you?
that after setting for hours /etc/rc.d/cron stop works?
(I had one sitting overnight, worked.
yes, I want to know why.. I suspect its some combination of something
rc. calls (something in my /usr/local/etc/rc.d dir)
but don't know why it 'hangs around'. maybe one of those rc scripts
sets something bad.
