ScratchOS

A simple, easy-to-use distro with minimal headache. :)

ScratchOS (SOS) is a project and accompanying handbook designed to take you from a standard Linux host to a fully functional, custom-built operating system.

Purpose

The purpose of this project is to provide a clear, linear, and beginner-friendly path through the process of building ScratchOS. Unlike traditional documentation that can be overwhelming with options, this guide focuses on a single, verified path to success.

My goal is to help you understand the internal workings of a Linux system by building it from the ground up, one package at a time.

Prerequisites

Before you begin the handbook, ensure you have the following:

1. A Host Linux Distribution: You need an existing Linux system (like Debian, Ubuntu, or Fedora) to act as your building environment.
2. Basic Command Line Knowledge: You should be comfortable using a terminal and running commands as root or using sudo (i.e.: ls, cd, cat etc, everything else is taken care for you ;) ).
3. Host Development Tools: Your host system must have essential build tools installed (e.g., bash, binutils, gcc, make, etc.).
4. Disk Space: At least 20-30 GB of free space on a dedicated partition.
5. Patience: Building an OS takes time. Don't rush!

The Handbook

The Handbook/ directory contains a step-by-step guide to building ScratchOS.

To get the most out of it:

1. Follow the Order: Start at Handbook/000-Index.md or Handbook/001-Introduction.md and move through the chapters sequentially.
2. Read the Explanations: Every step includes a "Purpose" section. Understanding why you are running a command is just as important as running it correctly.
3. Copy-Paste Carefully: While we provide command blocks for ease, always double-check the variables before executing.
4. Verify Outcomes: After each major step, ensure the "Expected Outcome" matches your experience.

Expected Outcome

By the end of the handbook, you will have:

• A functional, self-hosted Linux system named ScratchOS.
• A custom-compiled Linux kernel tailored to your needs.
• The systemd init system managing your services.
• A deep understanding of how the various components of a Linux system fit together.
