create a new user, then edit /etc/passwd and set his uid to 0. However, if you try to change this user's password, it will change root's password instead. The only way to change this user's password is by directly editing /etc/shadow.
I don't think I need to tell you that you should not do this.
$cp /bin/bash /home/foo #chown root /home/foo/bash #chmod +s /home/foo/bash

this is a security precaution. bash ignores a setuid flag on itself.

you can do "passwd new-root-user" and it will change the password of the new-root-user, even if the uid is 0; it will not change the password of root. At least in my system (Debian 2.2 with kernel 2.4.12) it works that way.

well, the way passwd works is it first checks the uid of the user, and then changes the password of the first user it finds with that uid. that's how it worked for me when i tried it - more than four score and several moons ago.
Hello,
well, the way passwd works is it first checks the uid of the user, and then changes the password of the first user it finds with that uid.
In the sources of passwd there is the following line, with comments:
static char *name; /* The name of user whose password is being changed */
I have not read the full source file, but from the comment, and the way passwd works in my system, I see that the program changes the password according to the user name, and not the uid. That is a better behaviour, I should say.
