Automatic login to virtual console

Warning
Automatic logins pose security risks. Anyone who can start the computer can get access to the operating system. Consider a BIOS password for additional security.

Gentoo supports different init systems. Each init system requires their own solution for auto-login.
All involve passing --autologin <username> to the terminal handler called agetty, but how this is done differs per init system

Edit /etc/inittab as follows:
FILE
/etc/inittab# TERMINALS
c1:12345:respawn:/sbin/agetty --autologin <username> --noclear 38400 tty1 linux
c2:2345:respawn:/sbin/agetty 38400 tty2 linux

c5:2345:respawn:/sbin/agetty 38400 tty5 linux
c6:2345:respawn:/sbin/agetty 38400 tty6 linux
openrc-init
Start with the openrc-init instructions, and adapt it for auto login on the first tty as follows:
Create a file /etc/conf.d/agetty-autologin:
FILE
/etc/conf.d/agetty-autologinagetty_options="--autologin <username> --noclear"
Replace the agetty.tty1 service with one called called agetty-autologin.tty1:
root #cd /etc/init.d
root #rc-config delete agetty.tty1
root #mv agetty.tty1 agetty-autologin.tty1
root #rc-update add agetty-autologin.tty1 default
