The file /usr/lib/systemd/system/nut-driver.service contains this



[Unit]
Description=Network UPS Tools - power device driver controller
After=local-fs.target network.target
StopWhenUnneeded=yes

[Service]
ExecStart=/upsdrvctl start
ExecStop=/upsdrvctl stop
Type=forking





I created an override with the appropriate ExecStart and ExecStop lines, as
thus:

[Service]
ExecStart=
ExecStart=/usr/lib/ups/driver/upsdrvctl start
ExecStop=
ExecStop=/usr/lib/ups/driver/upsdrvctl stop


which makes the *proper* unit file:




[Unit]
Description=Network UPS Tools - power device driver controller
After=local-fs.target network.target
StopWhenUnneeded=yes

[Service]
ExecStart=/usr/lib/ups/driver/upsdrvctl start
ExecStop=/usr/lib/ups/driver/upsdrvctl stop
Type=forking
