Good job looking up that old post. Yes, mostly because of static vs. dynamic, I believe that it's a mistake to change root's shell. But as I mentioned, there are other problems as well.

Well, yes, but it's misleading to phrase the question like that. I believe that it is dangerous to run as root because root has too much power. This forum is full of questions from people who screwed up their system by mistyping a command as root. It is not because of which shell you are using.

This is a general principle that applies to any system. Microsoft cautions against running as administrator on NT/XP for the same reason.
