Save the below content as /usr/lib/systemd/system/nut-driver.timer <----cut from here ---> [Unit] Description=Delay startup of nut-driver by as many seconds as specified in the [Timer] section Documentation=https://www.freedesktop.org/software/systemd/man/systemd.timer.html [Timer] OnBootSec=20 <--- to here ---> 2. Run the following commands: #systemctl disable nut-driver #systemctl enable nut-driver.timer #reboot? ## for testing purposes; you can also emulate by adding ??? ??? ??? ??? ??? #for testing purposes ??? ??? ??? ??? ??? OnActiveSec=20 to the [Timer section] That should do it. wolfy
