Description of problem:

systemd does not remove empty private tmp directories.

tmpwatch has to do that for systemd, but as it has a 30 day default on Fedora,
the system ends up with 200.000 empty directories in /tmp/ and /var/tmp/ ( not symlinked ) 

a time sorted directory list reveals, that this only applies to direcotries in a specific timeframe :

Version-Release number of selected component (if applicable):

systemd-44-24.fc17.i686

Actual results:

uptime = 3 days

# ls -la /tmp/ | grep -c systemd
6693
# ls -la /var/tmp/ | grep -c systemd
6690          

Expected results:

at best only the active directories.

Additional info:

I wasn't able to determine which cronjobs/task did create these directories.
None of my cronjobs does produce 35 systemd starts per minute.

On one server, it takes ages to get them removed with tmpwatch, on others it's done in seconds.

Comment 1 Michal Schmidt 2013-07-22 08:51:52 UTC

In Fedora 18 and later, systemd cleans up services' private tmp directories after stopping them. This should fix the problem you're having.

Since the end-of-life for Fedora 17 is only a week away, I do not expect the fix to be backported in time.
