# Automate Red Hat Enterprise Linux RHEL Installation with Kickstart

As the demands of modern digital infrastructure grow, the need for
efficient and standardised methods of operating system deployment
becomes increasingly important.

The Kickstart method is a powerful tool that allows system
administrators to automate the installation of Red Hat Enterprise
Linux (RHEL) on multiple machines.

This Attune Project contains Blueprints to create RHEL Kickstart ISOs.

## About Red Hat Enterprise Linux

RHEL stands as a commercial Linux distribution meticulously crafted by Red
Hat to cater to the business sector. This versatile operating system comes in
server editions designed for various architectures, including x86-64, Power
ISA, ARM64, and IBM Z, as well as a desktop edition tailored for x86-64
systems. The development and innovation for RHEL draw inspiration from Fedora
Linux and CentOS Stream, which serve as its primary sources for new features
and enhancements. Red Hat places its paramount emphasis on providing
comprehensive support, training, and certification programs exclusively
centered around the RHEL platform.

## Understanding Kickstart Automation

Kickstart is a technology developed by Red Hat that enables
administrators to automate the installation process of RHEL.
Instead of manually configuring each installation, Kickstart uses a
predefined configuration file, commonly referred to as a Kickstart
file, to specify various installation settings. These settings
include language preferences, partitioning schemes, package
selection, network configuration, and more. The Kickstart file
essentially scripts the installation process, allowing for
consistent and repeatable deployments.

## Advantages of Automated Kickstarting

Automating the installation of RHEL using Kickstart offers several
key benefits:

1. **Time Efficiency:** Manual installation can be time-consuming,
especially when dealing with multiple machines. Kickstart
automates the process, saving significant time and effort.

2. **Consistency:** Automated installations ensure that each
instance is configured identically, reducing the risk of errors
caused by manual intervention.

3. **Reduced Human Error:** Manual installations can lead to
mistakes or variations in configuration. Kickstart eliminates these
errors by following a predefined script.

4. **Standardisation:** Kickstart promotes standardized
configurations across the organization, simplifying management and
troubleshooting.
