If you read the 'su' manpage, it says that IF the group '0', which usually corresponds to the 'wheel' group is missing, any user can use 'su'. I don't want to try removing group '0' on my machine, 'cause I'm pretty sure my 'root' account (and all the other accounts in the wheel group will be useless after that). I wonder what exactly this means. I don't remember seeing any option for creating/not-creating the wheel group while installation.
