There is a quick tool in the GUI for the modification of the start up boot process. But for a more concise editing of the start-up processes, we will use the terminal-based utilities.
1. Install sysv-rc-conf. It is a Perl script boot process tool.
sudo apt-get update
sudo apt-get install sysv-rc-conf
This tool can easily configure the boot process and other start-up tasks. Now lets run it:
From there, you can manually set what processes you want to run at boot-time, by changing the runlevel values. Leaving it blank means it will not be executed at next restart, subsequently.
2. Limit the teletypes. You’ll have to edit the inittab file.
sudo pico /etc/inittab
Comment out tty3 – tty6. Leaving two vts (terminals) would be enough, and most of us don’t even know that exist. Save the file.
Reboot to see the changes!
