[systemd-devel] Q: "systemd[1]: var-tmp-AP_0x6tWaHS.mount: Succeeded."

[Ulrich Windl]

Hi!

When upgrading SLES15 to SP3, a newer version of systemd was installed (246.16+suse.191.g3850086c65).
Since then I see new journal messages like these that I cannot associate with a unit:

Jan 27 09:29:30 h16 systemd[1]: var-tmp-AP_0xC5KDJP.mount: Succeeded.
Jan 27 09:29:30 h16 systemd[22591]: var-tmp-AP_0xC5KDJP.mount: Succeeded.

Where do these messages originate from, and couldn't they be improved? Or is it some debug-leftover?
I do not see corresponding names in /var/tmp.

Regards,
Ulrich
