But there are programs that don't use su -s. E.g., custom logins (non-anonymous) from wu-ftpd will fail if the login shell is set to /bin/false. This, of course, is probably a bug, but I suspect a lot of things will break if (some) system users have no shell. T -- WINDOWS = Will Install Needless Data On Whole System -- CompuMan
