Actually there is a problem here: with transparent mounting, the
translator gets a port to the real underlying node. However, the real
underlying node is meaningless in this case, as we don't even include it
in the union. Effectively, we use the explicitely included directory as
underlying filesystem.

I wonder whether passing, when there is no -u, a port to the first
"normal" directory in the union instead, would suffice to make things
behave as expected? Or would it cause even more confusion?...
