Why would Carl want to do this?  Well, I know of a really good 
reason.  When you maintain a server located at a customer site with an 
admin on their side that likes to hack and destroy, you give him a super 
user account but not ultimate root.  I have that same situation right now 
that their admin fubar'd the system and locked root bash_history into 
/dev/null because he was mistakenly given "root" password instead of using 
his super user account.  It's now not bringing up the programming and I am 
waiting for my sys admin to return from out of town.

I certainly wouldn't want to delete any root account because it give you 
less control over what's happening if you don't have possession of the 
server.  It's a scary world out there!
