Yes, it would take a new errno to do it right, and then we would have to
agonize over the prospect of bloating the syserrlist. Eventually we will
realize that error message management is a real service in its own right,
and start trying to find a way to avoid producing whole booklets of error
messages, like MacOS and Windows.

One compromise would be to create a new errno for all foreign filesystem
problems of this sort: "Operation not allowed by foreign filesystem"
