Modify root password on MacOS X

Question

On a Mac I do not have the root password, but I have a user with administrative privileges.
Can I use it to reset the root password?

Thank's.

MacOS X 10.6.3

Answer 1

Are you sure your installation of OS X has a root user? It's disabled by default, and to run a command with root privileges the administrative user would use sudo instead, using their own password (which cannot be blank).

Answer 2

Should it not be: sudo passwd root
