Summary

As usual, we've seen some cool stuff in this chapter. We started out by looking at the systemctl commands for shutting down, halting, or rebooting a machine. We then saw that the old-style shutdown commands still work, and will allow you to use the scheduling and messaging features that you've always been used to using. We ended by creating a service that would run a job whenever you shut down the machine.

I realize that a lot of you might already have been familiar with a lot of what I presented in this chapter, but I did present some cool things at the end, and I hope that you enjoyed it.

This concludes part 1 of Mastering systemd. In part 2, we'll delve into the mysteries of cgroups. I'll see you there.
