[systemd-devel] After= and Wants= doesn't seem to have an effect

[Christopher Wong]

Hi,

I got a case were After= and Wants= doesn't seem to have an effect for the opticsd.service.

./info.log.1:2021-12-17T21:30:02.684+00:00  [ INFO    ] systemd[1]: Starting Iris detection...
./info.log.1:2021-12-17T21:30:02.884+00:00  [ INFO    ] systemd[1]: Starting Wiper power manager...

After=temperature-controller.service

# /usr/lib/systemd/system/temperature-controller.service
[Unit]
Description=Temperature controller
...
After=iris-detection.service
Wants=iris-detection.service

Is it possible that After= is ignored, even if Wants= is specified?

Best Regards,

Christopher Wong
