housekeeping-plugin dislikes systemd private namespace directories: Failed to enumerate children of /var/tmp/systemd-...
Submitted by Christian Stadelmann
With housekeeping-plugin enabled I often get lets of these warnings in syslog:
gnome-session: (gnome-settings-daemon:2266): housekeeping-plugin-WARNING **: Failed to enumerate children of /var/tmp/systemd-private-80cdc19ff585439e875829bf938b78c1-colord.service-WVom: Access denied
Those directories cannot be cleaned up since they are owned by root (and housekeeping-plugin is not run as root).
See downstream bug in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=988632
In my case the affected directories are: /tmp/systemd-private-* /var/tmp/systemd-private-* (rtkit-daemon.service, colord.service, cups.service) /var/tmp/kdecache-root /var/tmp/yub-abrt-* /var/tmp/abrt/* and some entries in trash://
