Hopefully somebody can shed some light on this for me. [/B]
Ok. I'll take a stab at this one. As Electro pointed out Windows (particularly the DOS-based W9x/me versions) clearly illustrates the dangers of running as root, but the connection isn't intuitive.
The fact that you're asking about file permission fundamentals leads me to believe that exploring this might be productive. (No offense)
Basically, you want to avoid running as root/Administrator/whatever because those accounts can literally do anything. This is very convenient, since the OS never tells you "no" - you are the god of your own little universe. On the other hand, it's very dangerous, since any program you run is god too, and can do anything it wants. Not to get too Biblical, but think Lucifer here.
Analogizing, running day-to-day activities as root is like using a surgical scalpel to butter your bread - No matter how frozen that butter is, you will
get your bread buttered. However, since butter isn't usually frozen your habit of using scalpels means you'll eventually slice off a finger - count on it.
Hope this helped... If not, I'll babble on.
