When Linux finishes the boot process it reads the file /etc/issue (and /etc/issue.net for remote logins) from where it can find the text to be printed on the login screen.
Although you can edit those files, it is way cooler to display a banner! =)
Let's get our hands dirty!
- apt-get install linuxlogo
- cp /etc/inittab /etc/inittab.bkp
- sed -i s'/\/sbin\/getty 38400/\/sbin\/getty -f \/etc\/issue.linuxlogo\ 38400/'g /etc/inittab
- init q && killall -9 getty # This will drop you off of the terminal.
I hope you can spread this with your friends! :)
