The reason it's gone is that we modified the interface used to determine if users can perform specific actions. Now, we just ask "can user X do this mount?". In the past, the same code was able to change the mount flags (to add nosuid,nodev). But with the new interface and our desire to limit what the access routines can do, they now can only say "yes" or "no." Because otherwise, the validation code could effectively say, "Yes, and while we're at it, let's get rid of nosuid and nodev". Take care, Bill
