title: Retrieve Default ACL in Python Using Posix 1e
body: <p>Using the <a href="http://pylibacl.k1024.org/module.html" rel="nofollow">posix 1e Python module</a> I am able to get/set the ACL for a file without having to spawn a subprocess and call <code>getfacl</code>/<code>setfacl</code>:</p>
  
  <pre><code>&gt;&gt;&gt; import posix1e
  &gt;&gt;&gt; acl1 = posix1e.ACL(file="file.txt") 
  &gt;&gt;&gt; print acl1
  user::rw-
  group::rw-
  other::r--
  </code></pre>
  
  <p>I can also <em>apply</em> a default ACL and <em>delete</em> it:</p>
  
  <pre><code>path = '/some/other/path/'
  acl1.applyto(path, posix1e.ACL_TYPE_DEFAULT)
  posix1e.delete_default(path)
  </code></pre>
  
  <p>However, <strong>I can not seem to work out how to <em>retrieve</em> the default ACL</strong>!  Does anyone know how this can be done using the posix 1e module?</p>
