It may well be that this will remain an issue about which reasonable folks can agree to disagree, and I am willing to accept that. I believe that, once again, "it depends". In the case of human behavior, I would be willing to accept that if the human behavior in question is possible because of either root or physical access to the machine, preventing fairly arbitrary "bad things" from happening is, indeed, impossible. However, if a non-root user with no physical access to the machine can cause undefined behavior, that's a bit beyond the level that I am willing to accept, and I will do what I can to help ensure that the system either runs correctly or (as a desperation maneuver) fails as gracefully as possible. david -- David Wolfskill dhw@whistle.com (650) 577-7158 pager: (650) 371-4621 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
