I tried to create a super user account using useradd command -> useradd superuser -g 0, but I guess it didn't create a super user account. It just created an ordinary account. I'd like to ask how to create super user/root-like account???
Actually, I'm just trying to create a root-like account in order so that if the ordinary users would want to be superuser, using the su command, they'll just have to enter that root-like account's password. Coz I don't want these ordinary users to be superusers by knowing and entering the root's password, instead they'll just become superusers using the capabilities of this another root-like account.
well, I just need normal user to be able to edit files that are not theirs, and make them able install softwares (like CVS versioning control system). I guess thats all they need to do when they make themselves superusers.
