[SOLVED] systemctl daemon-reload causes reboot flow

impossibleveins23 · 2025-06-22 19:47:19

Hi,

A few weeks ago I started experiencing systemd reloads which cause restart of services including unmounting volumes and user logout.
It seems the trigger is after pacman updates (which triggers systemd reload) or when restarting services.

This log is from disabling tccd:

I'm not sure exactly when it started so can't tie it to a specific systemd update or any specific package.

Found the cause for this: I had invalid lines in /etc/systemd/system/systemd-networkd-wait-online.service.d/override.conf
Fixing this instantialy solve this issue and I can run again without triggering restart flow:

systemctl daemon-reload

and:

systemctl daemon-reexec

How did you manage to troubleshoot this? I am facing the exact same issue. After a pacman update, systemctl daemon-reload is called automatically, which means it shuts down pacman and the DE mid update. The logs aren't giving me any hint as to what may be causing this. Sometimes manually doing a "sudo systemctl daemon-reload" will trigger it, but sometimes it doesn't.

Other than checking that all the services are configured correctly using `systemd-analyze verify`, I had another major issue that my /etc/crypttab had incorrect UUID for the encrypted partition (I switched hard drives).

derpva · 2025-10-27 15:38:50

I also had an incorrect UUID in crypttab after moving drives recently. Corrected it, now just need to wait some updates and hope it doesn't happen again. ✌?

Thank you.

Edit: Seems to have worked! Thank you again.
