The ``magicness'' of nobody comes from NFS, not VFS. Sun invented nobody as root's alter ego when remote requests come from a non-privileged client. (The futility of this approach should be obvious, but it seemed to help at the time.) It might be an interesting exercise for the people who are working on this sort of stuff, to come up with a mechanism whereby every object and every actor with a particular UID is considered distinct. (Probably ``actors'' need to be considered on the level of sessions rather than processes, in order not to break POSIX signal semantics.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
