title: saltstack: creating directory only if does not exists
body: <p>Currently I have the following rule for creating a directory</p>
  
  <pre><code>/init/dir:
    file.recurse:
      - source:  salt://init_dir/init
      - user:  name
      - group:  group
      - name:  /path/init
      - dir_mode: 2775
      - file_mode: 777
  </code></pre>
  
  <p>Now I want to create a directory on new minions only if the directory does not exists already. </p>
