title: touch tmp/restart.txt not working
body: <p>I'm hosting a rails 4.2 app on digital ocean, with the 1 click installer.</p>
  
  <p>At the beginning everything was working fine and I was able to restart by touching <code>tmp/restart.txt</code>, but now is not working, to restart my app I have to do <code>service unicorn restart</code>. </p>
  
  <p>Where is the configuration for this or how can I debug it?</p>
