[Bug 1484027] Re: systemd-tmpfiles-clean warns about duplicate /var/log line

[Heinz-Werner Seeck]

Addl comment which could be considered by a future fix...

The point and the issue of the problem in fact should address is the following - given the tmpfiles.d behaviour as follows in man -S5 tmpfiles.d:
...
Files in /etc/tmpfiles.d override files with the same name in /usr/lib/tmpfiles.
and /run/tmpfiles.d. Files in /run/tmpfiles.d override files with the same name in
/usr/lib/tmpfiles.d. Packages should install their configuration files in
/usr/lib/tmpfiles.d. Files in /etc/tmpfiles.d are reserved for the local administrator,
who may use this logic to override the configuration files installed by vendor
packages. All configuration files are sorted by their filename in lexicographic order,
regardless of which of the directories they reside in. If multiple files specify the same
path, the entry in the file with the lexicographically earliest name will be applied. All
other conflicting entries will be logged as errors.
...

Considering this, the /usr/lib/tmpfiles.d/00rsyslog.conf file in line 6 (delivered by rsyslog 8.16.0-1ubuntu3 package) to my perception is derived as effective line for /var/log, the /usr/lib/tmpfiles.d/var.conf file line 14 delivered by systemd
in the 229-4ubuntu10 package will cause the logging. Since that is an out-of-the-box setting,
there should be a discussion of the topic with decision to be taken among systemd and rsyslogd that ONE of the two parties is delivering a tmpfiles config only.

Title:
  systemd-tmpfiles-clean warns about duplicate /var/log line

Status in rsyslog package in Ubuntu:
  Fix Released

Bug description:
  Triggered by the two /var/log entries that were reported in
  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1434295, I get
  daily log messages from systemd-tmpfiles-clean saying:

  Aug 10 15:04:13 seraph systemd[1]: Starting Cleanup of Temporary Directories...
  Aug 10 15:04:13 seraph systemd-tmpfiles[5897]: [/usr/lib/tmpfiles.d/var.conf:14] Duplicate line for path "/var/log", ignoring.
  Aug 10 15:04:13 seraph systemd[1]: Started Cleanup of Temporary Directories.

  I don't know much about systemd, so I have no ideas for how to fix it,
  sorry.
