From Linux From Scratch build a minimal system for running my application. but struck on disabling root permission. Need my minimal lfs as ubuntu. when ubuntu boots login-screen displays when we enter username and password it will redirect to Desktop from ter when we open a terminal it will open as $--> non root-user from ter we access #--> root via sudo. Same as ubuntu when my lfs boots want to display my application [xinit-window launcher (same as login screen in ubuntu but, in my case with out asking user name and password)] and when i access terminal it should display as $--> non-root user then i want to use sudo to access root. Thanks
