I had (mistakenly) been under the impression that "nosetuid" merely meant "no setuid" (vs. "no setgid"). However, in _The Design and Implementation of the 4.4BSD Operating System_ (McKusick, et al.), on p. 223, the description of that flag reads: nosuid Do not honor the set-user-id or set-group-id flags for any executables on the filesystem. This option is useful when a filesystem of unknown origin is mounted. Thus, I see that I misunderstood the specification; I'm passing the information along just in case I wasn't the only one to have missed the point. david -- David Wolfskill dhw@whistle.com (650) 577-7158 pager: (650) 401-0168 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
