I don't think this is true.
Well, first, this only could possible be so reasonably in the root
directory of the translator.  And I think that looking up . with
O_NOTRANS gives you the translator's root node and not the underlying
node.  The purpose of O_NOTRANS is to not get to a translator _on top of it_
(who said there can only be one translator?).

So, looking up "." gives you the top most translator, and there is no way
back.  Looking up "." with O_NOTRANS gives you the current level without
going up.

Note that there is no way to get levels inbetween if the translators don't
provide them.

Mmmh, need to ponder this more.

Thanks,
Marcus
