It : seems that "read my lips: no new devices" should be an option you can : set from the very initial mount so that people can't also figure out : how to get root, remove a /dev entry and replace it with one of their : own. Come to think of it, there should also be a -o staticdev option : to disallow *any* changes after the initial mount. That would make : some of our more paranoid sysadmins happy. My concern is that I usually know what devices I want (/dev/null, /dev/zero, /dev/tty). That makes it harder to delete all of them not on the list.
