I still don't understand why this needs to be done differently with unionmount than without mounting. I either case, the list of filesystems needs do be kept consistent in the very same way I would think?... My guess would be that obtaining the root nodes at this place might be a good way to force the mountee startup at a defined place -- but according to your explanation this in not the purpose, so I really don't get it. -antrik-
