Boot Systems Into Different Targets Manually

Introduction

In this challenge, you will learn how to boot a Linux system into different targets (runlevels) manually. This is an essential skill for system administrators to manage and troubleshoot running systems. You will practice booting into different targets, such as the graphical target and the rescue target, and understand the implications of each target.

Skills Graph

Boot into the Graphical Target

Tasks

• Boot the system into the graphical target (also known as the graphical user interface or GUI).
• Verify that the system has successfully booted into the graphical target.

Requirements

• The default target for the system should be the graphical target.
• You should be able to log in to the graphical target using the labex user account.

Example

After booting into the graphical target, you should see the login screen, and you should be able to log in and access the graphical desktop environment.

Boot into the Rescue Target

Tasks

• Boot the system into the rescue target (also known as the emergency target).
• Verify that the system has successfully booted into the rescue target.

Requirements

• The system should boot into the rescue target, providing a minimal environment for troubleshooting and system recovery.
• You should be able to access the rescue target and perform basic system administration tasks.

Example

After booting into the rescue target, you should see a minimal command-line environment with limited services running. You can use this environment to perform system recovery tasks, such as mounting file systems, resetting passwords, or troubleshooting issues.

Summary

In this challenge, you learned how to manually boot a Linux system into different targets, specifically the graphical target and the rescue target. You practiced booting into these targets, verifying the successful boot process, and understanding the purpose and use cases of each target. These skills are essential for system administrators to manage and troubleshoot running systems effectively.
