    That is fine. As long as it is doing so in the _autofs_ filesystem. A
    call to 'stat()' should suffice to tell if this is the case.

    If the directory isn't accessible, then autofs shouldn't be trying to
    override that. It certainly shouldn't be doing so by trying to create
    the directory.
