title: Issues running cron in Docker on different hosts
body: <p>Im trying to get a docker container running to mange my cronjobs </p>
  
  <p>im running a very simple cron as a test in a docker container using centOS 6.5 base</p>
  
  <pre><code>* * * * * /bin/echo "it works!" &gt;&gt; test.log
  </code></pre>
  
  <p>it works fine if the container is running on CoreOS host, however if I run the container on a ubuntu 13.10 host the cron is not executed. (I though the host did not effect what was running in the container)</p>
  
  <p>both hosts are running docker 0.8</p>
  
  <p>am I missing something obvious, or it this a bug?</p>
  
  <p>thanks</p>
