Which can be seen easily with "ls -ln".

Depending on the exact algorithm used to get the username
corresponding to the UID, you may archive the result you want by
placing the line with the other name before the one with "root" in
/etc/passwd.

Which leads me to say that this is not a good idea to try to rename root.
