I have the same issue with light-locker since the last systemd update and I was wondering if there is any chance for the fix to be include in the systemd build soon?

Thanks !

Can also confirm that cherry-picking those commits worked and didn't break anything for me in two days of usage.

Would also like to confirm that I've been using these patches applied to systemd-243.78-2 for the past 3 days and the issue is gone. Everything seems to be working normally so far, no new breakage introduced.

I guess this is fixed with systemd 243.162-2?

Checking out e51d9bf9e5ac5a6618c175cd9b5cfdc6733cd5d1 I can still cherry-pick

Looking at the commit history from e51d9bf9e5ac5a6618c175cd9b5cfdc6733cd5d1 it seems that all relevant commits are included. I haven't tested 243.162-2 yet, but should be fixed.
