Hi, all -- I'm still a bit hung up on systemd :-( I've created a simple unit file diskfarm:~ # cat /etc/systemd/system/disks-timeout-set.service [Unit] Description=Set disk timeouts if needed [Service] Type=oneshot RemainAfterExit=true ExecStart=/usr/local/sbin/disks-timeout-set.sh [Install] WantedBy=multi-user,target which calls the script, which runs and exits. The script runs happily, and I can even systemctl start it with apparent success. I've tried to enable it diskfarm:~ # systemctl enable disks-timeout-set.service Failed to enable unit: Invalid argument without any luck, though. 1) A service is really what I want for a simple run-and-exit script, right? No other unit type makes sense. 2) So what's the error and how do I debug? I've surfed like crazy, but everything presumes a daemon and all of the "enable" examples always succeed :-) TIA & HANN :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
