Ah. You're right, of course. The critical bit I missed was that it's Plan 9 complaining, not vacfs (per se) or even 9p. I can't test vacfs on the Mac right now (9pfuse isn't getting along well with macfuse), but '9p ls' shows the full listing for / complete with anti-social files.
It would be nice if Plan 9's vacfs were a bit more helpful in this regard. I'll work up a patch soon. Anthony
