====== How to enable Autologin to Linux console using mingetty ======
The mingetty program is a lightweight, minimalist getty program for use on virtual consoles.

1) Install mingetty in Debian/Ubuntu
<code>
apt-get install mingetty
</code>

2) Update the /etc/inittab file by adding the following line to the end of the file:

Debian autologin by root:
<code>
T0:23:respawn:/sbin/mingetty --noclear --autologin root ttyO0
</code>

Ubuntu autologin by root:
<code>
1:12345:respawn:/sbin/mingetty --noclear --autologin root ttyO0
</code>

After reboot the bash shell will appear automatically without the essential login prompt.
