Hello, I have found some files/folders in /tmp that I thought they had to be deleted because of age. My /usr/lib/tmpfiles.d/tmp.conf is: # Clear tmp directories separately, to make them easier to override v /tmp 1777 root root 10d v /var/tmp 1777 root root 30d # Exclude namespace mountpoints created with PrivateTmp=yes x /tmp/systemd-private-%b-* X /tmp/systemd-private-%b-*/tmp x /var/tmp/systemd-private-%b-* X /var/tmp/systemd-private-%b-*/tmp And my /usr/lib/systemd/system/systemd-tmpfiles-clean.timer is: [Unit] Description=Daily Cleanup of Temporary Directories Documentation=man:tmpfiles.d(5) man:systemd-tmpfiles(8) [Timer] OnBootSec=15min OnUnitActiveSec=1d With these files I supposed that a file with more than 10 days in /tmp would be automatically deleted, but today I have found some files/folders with more than 10 days. What I have done wrong? Thanks.
