- Hi, welcome to Lesson 7.
If ever your Linux system gets in trouble,
it is very useful to know exactly what's happening
in the Linux boot procedure,
and that's exactly what we are going to do in this lesson.
I'll start by explaining the boot procedure
after which you'll learn how to manage systemd targets.
Next, I'll show you how to pass parameters
on the GRUB boot prompt
and you'll learn how to edit
GRUB configuration persistently.
We'll also have a look at legacy booting
as managed by init and upstart.
The last part of this lesson is about troubleshooting.
I'll show you when to use
which specific troubleshooting approach,
and you'll learn how to boot from a rescue disk.
This lesson ends with a lab
that helps you practice your troubleshooting skills.
