Did rsyslogd not create the device?

Nope, and when I ran an strace on rsyslog I did not see it fail in crating the device / socket.

Comment 4 Daniel Walsh 2014-09-10 12:08:45 UTC
After playing around with this for a while, I realized that rsyslog no longer listens on /dev/log by default it talks to journald, but journald is not running in your container, so you need to figure out how to get rsyslog to listen on /dev/log again.

Rsyslog guys how do I configure rsyslog to turn off journald support and back on /dev/log support?

Michal Schmidt says

In /etc/rsyslog.conf remove $ModLoad imjournal, set $OmitLocalLogging
to off and make sure $ModLoad imuxsock is present.

Also comment out:
$IMJournalStateFile imjournal.state

That should be about it.

This is a misconfiguration, not a bug.
