Hi, after examining the problem a bit further, I figured out that "/etc/init.d/ups-monitor" is executed by "/etc/init.d/halt" (which belongs to the package "initscripts")! I really do not understand how and why that happened but #670094 already handles that.
I am not really sure but it seems that "/etc/init.d/halt" is not
executed by systemd (which makes sense for me).
So I wrote a systemd-service "/etc/systemd/system/apcupsd-killpower.service"
[Unit]
Description=apcupsd: Ordering UPS to kill power (if onbattery/powerfail)
DefaultDependencies=no
Before=shutdown.target
[Service]
ExecStart=/etc/init.d/ups-monitor killpower
Type=oneshot
[Install]
WantedBy=shutdown.target
and did:
# systemctl enable apcupsd-killpower.service
Created symlink from
/etc/systemd/system/shutdown.target.wants/apcupsd-killpower.service to
/etc/systemd/system/apcupsd-killpower.service
But my first killpower-test gave me errors:
# journalctl | grep ups-monitor
Dec 11 18:50:42 server ups-monitor[2780]: apcupsd: Ordering UPS to kill
power... wall: cannot get tty name: Inappropriate ioctl for device
Dec 11 18:50:42 server ups-monitor[2780]: wall: /dev/pts/0: No such file or
directory
So I fixed "/etc/apcupsd/apccontrol" (see #709612):
# git diff /etc/apcupsd/apccontrol
diff --git a/apcupsd/apccontrol b/apcupsd/apccontrol
index 136ff36..b296f82 100755

echo "Warning communications lost with UPS ${2}" | ${WALL}
(I don't think that "wall" was ever needed so late in the shutdown process).
Please note that I first named the service "ups-monitor.service" which
seemed to conflict with "/etc/init.d/ups-monitor" but I didn't know
how to fix that...
As I am by far a systemd expert I would love to hear some comments on
this solution but at least this works for us. Thank you.
