title: Custom recipe order: launch before server restart
body: <p>I need to generate some config files on deploy but server won't start before I do that. </p>
  
  <p>I managed to get custom recipes to work and put them into <strong>Deploy</strong> group but they're being run after server restart. </p>
  
  <p>How do I make my recipes run on deploy before the unicorn restart task?</p>
