Help in root password
 

Hi all
When we install Linux, it will ask for root password.where will the password get stored and can we change the username root to anyother name(just changing the name alone)

you do *not* change the root username. sorry.

Where will be the passsword get stored?

passwords are stored in your password and shadow files, they are encrypted.

Thanks for the replies.
When user clicks on "OK" button after giving correct password, which script will run infront?. I am trying to add a new button to that login window for my code development. is it possible.where should i change.......

a password for what? what ok button? what script infront of what???

After giving root password (which was set during installation) in the login window, when user presses "OK" button to continue loading desktop, which script will run.
Where will the error message "invalid root name or password" is stored?
To that same window, i am trying to add a new button.

When you say "login window" you are dealing with a desktop environment (KDE, Gnome, etc.) or with a display manager (gdm, kdm, etc.)

Start with the scripts linked in /etc/rc5.d. On my system, there is "dm", which calls /etc/X11/prefdm. Let's assume that your system uses kdm. You'll need to get the source code for this, install your changes, and then re-compile. Google should be able to find the source.

Root does not run X server, meaning there is no need to use graphical logins for root.

You can run a GUI desktop as root (although some distros disable this by default). I'm setting up an ArchLinux system as we speak. I start the Desktop (kdemod) --as root-- using "startx".

Stupid thing to do. Getting into bad habits. If there was a single reason to run X as root, but there isn't. People with strong Windows background just cannot think in POSIX terms.

Now we're talking about what I SHOULD do....different question entirely. (I was only observing that it is possible.)

The example I quoted is a perfect example of when it can make sense to run a GUI as root. I am trying several different distros on a new laptop. No data, no other users. running everything as root makes it easier to do quick experiments.

My regular systems are set up in a way of which I think you would approve.
