+Re: Poweroff script / systemd [solved]
+Mon May 23, 2016 5:59 am
+
+I have finally been able to run my poweroff program as late as possible during the shutdown process with the following poweroff.service
+Code: Select all
+
+[Unit]
+Description=Turn power off after shutdown
+DefaultDependencies=no
+Before=umount.target
+
+[Service]
+Type=oneshot
+ExecStart=/usr/bin/python /opt/my_poweroff/my_poweroff.py
+
+[Install]
+WantedBy=halt.target poweroff.target
+
+Put this service into /lib/systemd/system, and a python script my_poweroff.py to be run at the end of the shutdown process into /opt/my_poweroff/my_poweroff.py
+
+Enable the service with
+Code: Select all
+
+cd /lib/systemd/system
+sudo systemctl enable poweroff.service
