Thank you very much for working on this, your work seems very interesting.

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 ?

Thank you.
