Systemd Restart= Configuration Not Doing Anything

Phx_Blaster007 · 2024-09-08 17:56:26

I am trying to make it so opentabletdriver.service does not automatically restart if I stop it manually, only restarting if something goes wrong.

I've done the following:
1. Set Restart=on-abnormal in /usr/lib/systemd/user/opentabletdriver.service. (Also tried Restart=no)
2. Run systemctl --user daemon-reload
3. Run systemctl --user stop opentabletdriver.service
4. Run systemctl --user status opentabletdriver.service
5. Wait a bit, then run systemctl --user status opentabletdriver.service again

The following is what i see at step 4:

phoenix@nyarch /u/l/s/user [3]> systemctl --user status opentabletdriver.service

And then at step 5:

Here is the contents of /usr/lib/systemd/user/opentabletdriver.service:

[Unit]
Description=OpenTabletDriver Daemon
PartOf=graphical-session.target
After=graphical-session.target
ConditionEnvironment=|WAYLAND_DISPLAY
ConditionEnvironment=|DISPLAY

[Service]
ExecStart=otd-daemon
Restart=on-abnormal
RestartSec=3

[Install]
WantedBy=graphical-session.target

And then of the override file at /home/phoenix/.config/systemd/user/opentabletdriver.service.d/override.conf:

[Service]
Environment=DISPLAY=:0

Any ideas?

If set to on-abnormal, the service will be restarted when the process is terminated by a signal (including on core dump, excluding the aforementioned four signals), when an operation times out, or when the watchdog timeout is triggered.

You *are* abnormal (lennarts words, not mine )
Try "on-failure" or "on-abort"

Actually the issue seems to be unrelated (although i think you're right that on-abnormal isn't correct). I couldn't get on-failure or on-abort to work, so I just decided to restart my PC, and surprisingly I found it working... but then I tried changing it back to Restart=always, and this time it after running systemctl --user daemon-reload and then stopping the service, it now never restarts. Restarting my PC caused it to automatically restart again. I am fairly certain now that the real issue is that systemctl --user daemon-reload is not working as expected, but I'm not sure why... Reloading results in the following output:

Sep 09 09:36:55 nyarch systemd[1155]: Reload requested from client PID 3284396 ('systemctl') (unit kitty-3161733-0.scope)...

No errors related to opentabletdriver, so it should be reloading... but it doesn't.

If you first reload the daemon and then restart the service, does the subsequent termination have the expected result?
Alternatively try "systemctl --user edit opentabletdriver.service" as it should correctly reload the service configuration.

Might be a systemd bug unexpected but correct behavior concerning the Restart condition and service edits since it's a somewhat special configuration.
