Merge lp:~jamesodhunt/ubuntu/trusty/upstart/periodic-logrotate into lp:ubuntu/trusty/upstart

[James Hunt]

We already provide a logrotate session job which runs soon after the user session has been created. However, it is never re-run.

It seems sensible that, like its /etc/cron.daily/logrotate system counterpart we run this job periodically to keep session jobs logs compacted. This would help with for example bug 1269838 (although may admittedly mask the issue to some degree). By creating this new job to handle the periodicity, it is easy for a user to modify the period:

    # change period to 5 minutes
    echo 'env ROTATE_SECONDS=300' >> ~/.config/upstart/periodic-logrotate.override

We could encapsulate all this within the logrotate job itself but 2 jobs allows the existing behaviour to be retained should that be desirable by simply disabling the new job:

   echo manual >> ~/.config/upstart/periodic-logrotate.override
