title: upstart logging output enabled
body: <p>Except doing explicit logging instructions like suggested in <a href="http://upstart.ubuntu.com/wiki/Debugging" rel="noreferrer">http://upstart.ubuntu.com/wiki/Debugging</a>, is there a way to enable output of what is happening with upstart?</p>
  
  <ul>
  <li>What event is raised</li>
  <li>What service changed its status (started/stopped/dead)</li>
  <li>What signal were emmited</li>
  <li>what output a service produced while starting</li>
  </ul>
