title: Redis starts manually with init.d but not on startup
body: <p>Redis properly starts up if I run the command:</p>
  
  <pre><code>sudo /etc/init.d/redis-server start
  </code></pre>
  
  <p>I've added my startup script with:</p>
  
  <pre><code>sudo update-rc.d redis-server defaults
  </code></pre>
  
  <p>But when I startup from a fresh boot, Redis isn't running. Where should I look to troubleshoot this?</p>
