Chapter 2: Understanding systemd Directories and Files

In this chapter, we'll explore the various systemd unit files and configuration files and explain the purpose of several types. We'll briefly look at some of the executable files that are associated with systemd. Along the way, we'll also look at the directories where these files live.

These are the topics we will cover in this chapter:

• Understanding the systemd configuration files
• Understanding the systemd unit files
• Understanding the systemd executables

The topics in this chapter comprise basic foundational knowledge of systemd. We'll be building upon this foundation in the chapters to come.

If you're ready, let's go.
