    <para>Cockpit provides a mechanism for checking if the current user satisfies a
      given criteria. Currently capable of checking for root users, and group
      membership. This is meant for updating UI elements based on what actions the
      user can perform. It is <emphasis>not an access control mechanism</emphasis>.</para>

      <para>Create a new permission object to check if the current user has permission.
        The "root" user is always given permission. The <code>options</code> argument
        can contain a <code>"group"</code> field, and members of that group are also
        given permission.</para>

    <refsection id="cockpit-permission-allowed">
      <title>permission.allowed</title>

        be <code>null</code> if the permission is unknown, or there was an error checking
        the permission or the permission data has not yet loaded. This property will update
        asynchronously and if you wish to be notified of changes connect to the
