On all my Red Hat Linux machines version 7.2 we saw that systemd-tmpfiles-clean.service is inactive:
systemctl status systemd-tmpfiles-clean.service ● systemd-tmpfiles-clean.service - Cleanup of Temporary Directories Loaded: loaded (/usr/lib/systemd/system/systemd-tmpfiles-clean.service; static; vendor preset: disabled) Active: inactive (dead) since Wed 2018-12-19 14:47:14 UTC; 12min ago Docs: man:tmpfiles.d(5) man:systemd-tmpfiles(8) Process: 34231 ExecStart=/usr/bin/systemd-tmpfiles --clean (code=exited, status=0/SUCCESS) Main PID: 34231 (code=exited, status=0/SUCCESS) Dec 19 14:47:14 master02.uridns.com systemd: Starting Cleanup of Temporary Directories... Dec 19 14:47:14 master02.uridns.com systemd: Started Cleanup of Temporary Directories.
It is strange that we saw the files and folders under
and it seems that cleanup is performed every some time.
I searched on crontab or cronjob, but I did not find other cleanup jobs.
Am I missing something here?
Is it possible that in spite of the service being inactive, the cleanup is performed every couple of weeks?
systemctl enable systemd-tmpfiles-clean.service The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...).
We also saw a few folders that were real old, as
