Does the statement by Mukund (below) mean that if root changes the uid of usershyam
to 40 (ie: <99) , then shyam becomes a super -user (he is alredy a super - useless ,
so root wants to make him a super -user) .

You can change uid by editing /etc/passwd ( I do not do it, as once I
suffered) , but if you try to create a user with same uid/gid with useradd
or adduser, it will refuse (that's better for health of linux box)
Therefore it is better to give maximum privilege to a user by uid=1 gid=0.
