Summary

All right, we've made it through another chapter, which is a good thing. In this chapter, we examined the structure of the service, socket, and path unit files. We saw the three sections of each type of unit and looked at some of the parameters that we can define for each of those sections. Of course, it's pretty much impossible to explain every single available parameter, so I've just shown you a few examples. And I'll show you more examples in the next few chapters.

An important skill for any IT administrator is knowing how to look up things that you don't know. That can be a bit of a challenge with systemd, because things are spread out over quite a few man pages. I've given you some tips on how to use the man pages to find what you need, which will hopefully be of some help.

The next skill you'll want to acquire is that of controlling service units, which is the topic of the next chapter. I'll see you there.
