Puzzle of the Day
The UNIX operating system (and most computer systems) have an
all-powerful user (root or operator or wheel).
- Why does such a user exist?
- Dennis Ritchie called the existance of this user "both a theoretical and
practical flaw." Why?
- If you were designing an operating system with security being a key goal,
could you avoid creating such a user? If so how? If not, how would you
implement the functionality of the root user?
