Chapter 9. init
"Uuno on numero yksi"
(Slogan for a series of Finnish movies.)
This chapter describes the init process,
which is the first user level process started by the kernel.
init has many important duties, such as
starting getty (so that users can log in),
implementing run levels, and taking care of orphaned processes.
This chapter explains how init is configured
and how you can make use of the different run levels.
