Soon after, you will see a message about init starting, followed by system
service startup messages, and finally you get a login prompt of some sort.

NOTE On Red Hat Linux, the init note is especially obvious, because it "welcomes"
you to "Red Hat Linux." All messages thereafter show success or failure
in brackets at the right-hand side of the screen.

Most of this chapter deals with init, because it is the part of the
boot sequence where you have the most control. init
There is nothing special about init. It is a program just like any other on the Linux system,
and you'll find it in /sbin along with other system binaries. The main purpose of init
is to start and stop other programs in a particular sequence.
All you have to know is how this sequence works.

There are a few different variations, but most Linux distributions use the System V
style discussed here. Some distributions use a simpler version that
resembles the BSD init, but you are unlikely to encounter this.
