Cool. > Please compare against the BSD sources if you get > a chance -- I hope I just misread the data structure. I will. I've got a couple NetBSD machines at home I can check, but I'd bet they're V2, and the bug was only in the V1 inode structure.

Unless my brain cells are dying of old age, I seem to remember that most implementations allow that behavior to be turned on or off in the file that defines the exports. And before this, I had been playing with the Plan 9 nfs server and came across how it squashes everything to none. Rob's comments seemed to indicate that the rationale was that UNIX security is too weak to be trusted in a Plan 9 environment. It was all that rolling around in my head that had me looking at it from that perspective. Thanks, BLS
