While I certainly agree that sudo has its advantages (see
http://aplawrence.com/Basics/sud.html ), it is indeed possible to
restrict users rights to use su - it's one of the attributes you can
set for any user. It's also possible to give a user specific root
privileges without giving them the root passwrd at all: See the man
pages for "asroot", "auth" and "authorize"
