Package running find /tmp /var/tmp -exec head -n1 '{}' \+ as root?

I just noticed a process running the following command or something similar while configuring htop:

find /tmp /var/tmp -type f -exec head -n1 '{}' \+

I think this is triggered by /usr/lib/tmpfiles.d/tmp.conf. Can anyone confirm this? Why does it need to run head on every single file in those directories?

Why would you think that? This isn't anything triggered by the tmpfiles binary.

That is the only thing that I have found so far that references both /tmp and /var/tmp.

I installed systemd and cronie this week. The process was automatically started and used enough cpu cycles to increase the fan speed. I think I would have noticed that before. I tend to check conky or htop whenever the fan takes off.

I don't know exactly what it was doing, but it's probably some housekeeping service or cronjob. I wasn't logged in as root at the time, so it can't have been any application that I was running (the only thing I sudo'd was pacman).

Of course, maybe I'm just losing my mind.

As falconindy says systemd-tmpfiles does not call find (or any other external binary). You could try systemd-cgls when the process to running to find its parent.
