If you are using X windows.
Enter /etc/rc.d/rc5.d
You can see that the filenames are started as 'k' or 's', meaning 'start' and 'kill'.
When you enter or exit a run-level, the system will kill the processes of the present run-level as the order of 'k' numbers ,then start the processes of the target run-level
as the order of 's' numbers.
So if you change the numbers in the filenames ,you can easily set the proirities or
privileges of your processes.
Be careful ! You can simply destroy your system by doing this !
