I am a bit late on the topic, but I would like to take advantage to ask a question I've been thinking of for much time. It might be a dumb question to your eyes, but it is not obvious for me : I've been annoyed in the past because I couldn't export two directories from the same filesystem with different credentials [1]. First, where does this limitation come from ? Then, is it possible to remove this limitation without being too intrusive in the VFS code ?
