I was disappointed when I saw that the systemd service units did not allow for 
adequate logging, so I use a custom version

  # nut-delayed-ups-shutdown.service
    Description=Initiate delayed UPS shutdown
    ExecStart=/usr/bin/logger -t nut-delayed-ups-shutdown "upsdrvctl shutting down UPS"
    ExecStart=/usr/sbin/upsdrvctl shutdown        # Debian

Note the line Before... to ensure that the logging goes to disk, and the first 
ExecStart... to get a trace of the action.

Maybe there are other options which do this more elegantly.
