&gt; From the sysadmin viewpoint, &#x2F;var is managed through &quot;retention&quot; (scheduled rotation, scheduled flushing, logrotate, crons, etc), and &quot;backups&quot; where needed.<p>Right. And &#x27;Docker for &#x2F;var&#x27; would be something that made all that easier. It would make it really easy to set up live, secure, restorable, backups of essential data; to rotate, compress, and delete logs; to extract all important logs to a separate host, and aggregate and index them, etc. At the moment, a configuration management tool can help you set this up, but you still have to write the configuration management script by hand.
