Ubuntu and many similar linux variants determine what daemons and scripts are run at boot time by placing links to /etc/init.d
scripts in the /etc/rc*.d/
directories. While you can certainly manage these links yourself (links starting with S are run at boot time and links starting with K are killed at shutdown in the other given by the number that follows the S or K), it can be hard to know the order in which the scripts should run. The Boot-up Manager is a graphical interface to the startup scripts that makes life easy. You can find it in the Systems
menu if it is installed.
0Example: turn off kvm at boot
