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. Igor
