The boot process is the genesis of a running Linux system. In this hands-on lab, we will examine the boot process on a RHEL 8 system. We will boot, reboot, and shut down a system normally, as well as boot systems into different targets manually.

- Work with `systemctl` System State Commands
- Investigate the systemctl options for power management.
- Look up the options for shutdown messages.
- Test out a shutdown and reboot with a shutdown message.
- Query and Set the Default Target of a System
- Query the default target of the system.
- Change the default target.
- Reboot and query the new default target.
- Work with the Traditional System State Commands
- Investigate the particulars of the power management utilities.
