README-SLACKWARE
Written by Robby Workman <rworkman@slackbuilds.org>
First, see /usr/doc/apcupsd-3.14.0/examples/make-hiddev if you're using
a 2.4.x kernel and need to manually create the device node(s).
Second, you'll need to start the apcupsd service at boot.
The recommended way is to add the following to your /etc/rc.d/rc.local
script:
if [ -x /etc/rc.d/rc.apcupsd ]; then
/etc/rc.d/rc.apcupsd start
fi
Make sure the rc.apcupsd script is executable.
Finally, you'll need to edit your /etc/rc.d/rc.6 script for apcupsd
to perform the shutdown on power failures. Here's the short version:
Scroll down to the end of rc.6 - you should see a section that calls
/sbin/genpowerd. Comment out (or remove) this entire section:
if [ -x /sbin/genpowerd ]; then
# See if this is a powerfail situation:
if /bin/egrep -q "FAIL|SCRAM" /etc/upsstatus 2> /dev/null ; then
# Signal UPS to shut off the inverter:
/sbin/genpowerd -k
if [ ! $? = 0 ]; then
echo
echo "There was an error signaling the UPS."
echo "Perhaps you need to edit /etc/genpowerd.conf to configure"
echo "the serial line and UPS type."
# Wasting 15 seconds of precious power:
/bin/sleep 15
fi
fi
fi
Now replace that section with this (or add immediately after it if you
chose to comment out the original):
# This will cause the UPS to kill the power supply after a configurable number
# of seconds (see the apcupsd.conf file). This is important for situations
# where the mains power comes back before the UPS batteries are completely
# dead.
if [ -f /etc/powerfail ]; then
echo
echo "apcupsd will now power off the UPS"
echo
/etc/apcupsd/apccontrol killpower
echo
echo "Please ensure that the UPS has powered off before rebooting."
echo "Otherwise, the UPS may cut the power during the reboot."
echo
halt -f -p # power down the system if the hardware is capable
fi
