I thought we were desupporting multiple filsys entries.

ENOENT is probably the right thing to do. The behavior we want to
simulate would be the same as if a local directory did not exist.

As I've said in other forums, I think that our user base has
significantly changed that a temporary homedir session with an xterm
is not that useful. Frankly, a web browser in kiosk mode would be
much more useful, IMHO. But that's probably a more in depth
conversation than wants to happen here.
