Code: $ sudo becomeroot # (modify random bytes) # exit $ No danger in going online with a root shell open, unless you run "browser" or something from a root terminal. This would cause the browser to run as root.
$ sudo becomeroot # (modify random bytes) # exit $
Of course, you should only work as root when you need to. Personally, I don't believe there is anything you can do as root that cannot be fixed with a reflash. Well, maybe if you TRIED to damage hardware or modify the bootloader or something...
