Thank you for your advices. If this is the right place (or tell me if it is 
better to continue this discussion privately), I would have three questions:

- why /bin/sh is intentionally minimalist? Which are its main purposes?
- why do you suggest /bin/sh as default shell for root?
- do you suggest to seldom use the root account in order to prevent some system 
damages, like in the other *nix systems, or for other reasons?
