Bug#847448: systemd: wrong permissions on non-persistent /run/log/journal

[Dennis Schridde]

Package: systemd
Version: 215-17+deb8u5
Severity: important

Dear Maintainer,

I tried to run `sudo -u nobody -g systemd-journal journalctl --unit=some-system-unit.service`, but journalctl replied "No journal files were found.". If I change the group argument to "root", I can read the journal of that unit. I would expect that some non-root user could
 read the journal, though, in this case to run a script as non-root that is supposed to send part of the journal via email.

The cause appears to be that /run/log/journal is owned by root:root instead of root:systemd-journal. There exists an older bug (bug #746279) where this was fixed in systemd 208-6, but the issue is back in systemd-215-17.

Best regards,
Dennis
