title: cant start mongodb strange behavior permission denied as root
body: <p>Im running as <code>root</code> on a smartos64 machine.</p>
  
  <ul>
  <li>My database is at <code>/data/db</code></li>
  <li>Mongod is at <code>/mongo/bin/mongod</code></li>
  </ul>
  
  <p>I get a 'permission denied' error with no further details when running either
   - <code>run ./mongo/bin/mongod</code> <em>or</em>
   - <code>sudo ./mongo/bin/mongod</code> </p>
  
  <p>I tried changing permissions with chown on <code>/data/db</code>, but I still get this behaviour. How would I start mongo?</p>
