Next, you'll find out how to analyze and fix boot-up challenges and set system parameters. An overview of cgroups that'll help you control system resource usage for both processes and users will also be covered, alongside a practical demonstration on how cgroups are structured, spotting the differences between cgroups Version 1 and 2, and how to set resource limits on both. Finally, you'll learn about the systemd way of performing time-keeping, networking, logging, and login management.

Technical requirements

We won't need anything fancy for this chapter. Just use your normal Alma and Ubuntu Server virtual machines, and it will all be good. Well, let me rephrase that. You'll want to use Ubuntu Server for the logind.conf demos, because restarting the systemd-logind service is problematic on graphical mode machines (I'll explain more about that in a bit). At the end of the chapter, there will be a couple of demos for which it will be handy to have a desktop interface, so you'll want an Alma machine with the Gnome 3 desktop for them.

All right, let's begin by looking at the systemd-logind.service file.
