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

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