Help needed modifying shutdown scripts
I am trying to use some custom startup+shutdown scripts to control a Belkin UPS using the nut utility. Essentially to achieve what is shown in point 4 of http://quasar.mathstat.uottawa.ca/~selinger/ups/belkin-universal-ups.html Before continuing, here is the output of uname -a: FreeBSD magellan.dom.bishnet.net 5.2.1-RC2 FreeBSD 5.2.1-RC2 #1: Sun Feb 22 02:52:35 GMT 2004 [EMAIL PROTECTED]:/u2/usr/obj/u2/usr/src/sys/MAGELLAN i386 The startup section is working fine, I created my own script in /etc/rc.d and it runs at the correct time. The shutdown bit however is causing me problems, I inserted my code into rc.shutdown under the section headed # Insert other shutdown procedures here Since FreeBSD doesn't seem to remount disks read-only during this script I first unmounted all unnecessary partitions and then made sure /, /usr, /var were all mounted read-only, as these are needed for the UPS driver to run. The UPS driver runs as expected and sits there monitoring battery power, however I get a fair few processes exiting on signal 11 which is worrying and then more worrying is that it kills the driver, and completes halting the system. Once in this state the system will never come back when AC power returns which is of course not desirable. Here is console output from around the point of the driver starting onwards: (Currently the script calls mount with no arguments so I could check that the mounts were as I expected, hence the mountpoint entries) pid 478 (mountd), uid 0: exited on signal 11 /dev/ar0s1a on / (ufs, local, read-only) devfs on /dev (devfs, local) procfs on /proc (procfs, local) /dev/ar0s1f on /usr (ufs, local, read-only) /dev/ar0s1d on /var (ufs, local, read-only) Waiting for AC power, or for UPS batteries to run out...

Most importantly can anyone tell me how to stop the system being shutdown before rc.shutdown terminates? (the UPS driver stays in foreground until the battery runs out, unless AC power returns in which case it calls reboot) I'm guessing that all the sig 11s are due to filesystems being mounted read only, but what I don't understand is why these processes are even still running? All of these processes are controlled by rc.d and looking at rc.shutdown they should have been stopped before the section I've placed my code is reached. ie in the section: # Determine the shutdown order of the /etc/rc.d scripts, # and perform the operation This got me curious so I created a simple test script which was a copy of the original rc.shutdown with the watchdog timer bits removed and the running of rc.d script shutdown set to simply echo the command instead, when run it output this: run_rc_script /etc/rc.d/exim stop run_rc_script /etc/rc.d/inetd stop run_rc_script /etc/rc.d/localpkg stop run_rc_script /etc/rc.d/jail stop run_rc_script /etc/rc.d/cron stop run_rc_script /etc/rc.d/local stop run_rc_script /etc/rc.d/nfsclient stop run_rc_script /etc/rc.d/ipfs stop run_rc_script /etc/rc.d/random stop run_rc_script /etc/rc.d/swap1 stop . This seems to be a rather small subset of the scripts in rc.d that are run on startup, and notably excludes commands to stop all the processes I was getting sig 11s from. Am I missing something here? So in summary, the most important thing I wish to fix is to stop the OS from halting whilst the UPS driver is still running as at the moment it leaves me with the possibility of the system not resuming unattended. The less important aspect is stopping the sig 11s from those processes as it would be nice not to get a whole bunch of .core files in my / ;-) However I can live with them if I have to.
