That's an interesting idea. I'm not sure of its feasibility though.
In my understanding in Hurd the filesystem shares the namespace with
ports (i.e. not every port is associated with a file, but every file
is associated with a unique file port). So in order to make some
application think that / is another directory, there has to be a mechanism
that intercepts filesystem name lookups and returns the appropriate port.
(Please correct me if I'm wrong).
File name lookups usually happen through the *fs translators so to support
it universally one would have to insert an intermediary between a name
lookup call and the translator call back.
