While the intent of preventing root is admirable, in practice it means that you 
have to type in the root password repeatedly when doing system configuration, 
since every tool is going to ask for it. The previous pop-up warning was 
probably as effective for competent people, and incompetent people shouldn't 
have root anyway.
