RH304 – New Features in Red Hat Enterprise Linux — Lesson 1: RHEL 10 Overview, Platform Changes, Installation, Kickstart, and Lifecycle

Learning Objectives

• Explain the architecture, purpose, dependencies, and expected behavior of RHEL 10 changes, installation, and Kickstart.
• Apply package mode and lifecycle while preserving reviewable technical evidence.
• Recognize and correct the condition where an unstated prerequisite or ownership gap causes the initial design to be incomplete.

Detailed Topics

• RHEL 10 changes: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• installation: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Kickstart: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• package mode: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• lifecycle: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates rhel 10 overview, platform changes, installation, kickstart, and lifecycle by tracing architecture, commands, configuration, system messages, and evidence. The walkthrough tests how an unstated prerequisite or ownership gap causes the initial design to be incomplete and explains how to isolate the cause without masking related issues.

Hands-On Exercise

Establish a controlled baseline for RHEL 10 Overview, Platform Changes, Installation, Kickstart, and Lifecycle and add the verified result to the RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap.

1. Confirm scope, versions, access, dependencies, assumptions, and acceptance criteria.
2. Perform the workflow while recording commands, configuration, output, events, and decisions.
3. Test the normal path and one course-specific exception or boundary condition.
4. Retest the correction and document rollback, ownership, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences RHEL 10 changes in the stated scenario.
• Compare two approaches for package mode and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, scope, identities, prerequisites, and starting conditions separately, then correlate logs, events, commands, metrics, and configuration history. Treat the assumption that an unstated prerequisite or ownership gap causes the initial design to be incomplete as a hypothesis until a reproducible retest confirms the cause.

Validation Checklist

• The required architecture, scope, identities, prerequisites, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap links conclusions to commands, configuration, logs, metrics, or other objective evidence.
• Corrective actions, rollback, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply RHEL 10 Overview, Platform Changes, Installation, Kickstart, and Lifecycle, explain the observed platform behavior, and support the result with a reviewable RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap.
