    True.

    There have been some changes in this area (David Howells made some
    changes which affected autofs4) and I'm not sure that the autofs module
    was reviewed. I didn't look closely at it at the time, I guess I should
    have. Sorry.

    It will take a while longer to work out if the autofs if open to the
    same issue resulting from Davids change.
