title: "No Top file or external nodes data matches found" setting up gitfs with SaltStack
body: <p>I've setup git on an nfs server. The salt master auto-mounts the folder containing the git repository on boot. I have copied .sls files, templates and scripts to the git directory and added them to git. </p>
  
  <p>I have added the following to the master config file, according to the guide <a href="http://docs.saltstack.com/topics/tutorials/gitfs.html" rel="nofollow">here</a>:</p>
  
  <pre><code>fileserver_backend:
    - git
  
  gitfs_remotes:
    - file:///mnt/git-repo
  </code></pre>
  
  <p>I am in doubt about what to set file_roots to, but have tried both  </p>
  
  <pre><code>- /srv/salt
  </code></pre>
  
  <p>and</p>
  
  <pre><code>- /mnt/git-repo
  </code></pre>
  
  <p>with same result: "No Top file or external nodes data matches found"</p>
  
  <p>SaltStack version is 0.17.4, OS is SLES 11.2.</p>
  
  <p>Does anyone know where I have gone wrong?</p>
