Let me put it differently. Root's UID is 0 - suppose I change UID 0's User 
Login to 'doorknob' - first, can this be done? Second, would I have to create 
a new home directory called 'doorknob'? Third, are there any implications, 
doing this, for other software and/or settings in a Linux PC? Fourth - if 
this shouldn't be done, can a new user, say UID 15, be created with all the 
same privileges as root, and can root then be purged?
