As the headline says, this article will free you from ever
having to type your name and password at the console again:
"When you boot Linux, do you get a "login:" prompt on a
bunch of virtual consoles and have to type in your username and
password on each of them? Even though you're the only one who uses
the system? Well, stop it. You can make these consoles come up all
logged on and at a command prompt at every boot.
In case you're thinking that password prompt is necessary for
security, think again. Chances are that if someone has access to
your console keyboard, he also has access to your floppy disk drive
and could easily insert his own system disk in there and be logged
in as you in three minutes anyway. That password prompt is about as
useful as an umbrella for fish.
The method I'm going to describe for getting your virtual
consoles logged in automatically consists of installing some
software and changing a few lines in /etc/inittab. Before I do
that, I'll take you on a mind-expanding journey through the land of
getties and logins to see just how a Unix user gets logged in."
