Description Zbigniew Jędrzejewski-Szmek 2021-06-01 15:30:01 UTC 
Description of problem:
Holy moly, why involve udev in this at all? Please just check the kernel command
line when starting sddm. And if sddm cannot check itself, do it in ExecStartPre=.
There is really no need to touch the file system on every udev add, remove, change, bind, and unbind event.

Version-Release number of selected component (if applicable):
sddm-0.19.0-13.fc34.x86_64
