[SOLVED] systemctl daemon-reload causes reboot flow

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
