Help in root password

[East]

When installing linux, it will ask for root password. can anyone point out where the password will be maintained? and instead od root as user name can we change it to anything(just name only) ?

You should not replace root username with custom username. root password is stored in encrypted form in /etc/passwd and /etc/shadow files.

You can assign root privileges to any Regular User.

Theoretically you could change the root username to whatever you want, but I would advise against this because some programs may not work correctly if they specifically look for a user called "root" and that user can't be found. /etc/shadow contains all encrypted passwords (it used to be in /etc/password before encryption became the norm). Also look at the passwd and chage commands if you want to manage passwords on your system.

Don't! The root account isn't a user account. It's user #0; the system account. When you're running as root the system no longer sees difference between itself and you, which is a bad thing unless it's absolutely necessary.

You may brake your own system as often as you like (I know I have ), but I wouldn't put any effort into making this easier

The permission system takes a while to get used to, but it's well worth the trouble IMHO
