I'm not sure if this is specific to Redhat, but I'll start here.

I've changed the passwd file to no nologin for root and now when I boot up I get a message that adminsitrator has blocked login, I OK this and get the login screen, then I can log in OK as the users I created.

The question is, how do I stop the boot up process trying to go in as root before the login screen opens?

Thanks
