Linux From Scratch — The Complete Series ✅

A 12-part series documenting a complete Linux From Scratch (LFS 12.3) build. From an empty disk to a bootable operating system, every package compiled from source.

Status: COMPLETE 🏁

Phase 1: Foundation

Understanding Linux and preparing to build.

  1. Why Build Your Own Linux — The case for building your own operating system from source code
  2. How Linux Actually Works — Kernel, userspace, system calls, and the architecture beneath every distro
  3. Preparing the Build Environment — Partitions, directory hierarchy, and a clean build user

Phase 2: Building

Creating the tools to build the tools.

  1. Building the Cross-Toolchain — GCC and Glibc targeting our new system
  2. Temporary Tools — A minimal set of utilities independent from the host
  3. Into the Chroot — Entering the new system and leaving the host behind

Phase 3: The System

Building every package for real.

  1. Building the Core — Final GCC and Glibc — the foundation of everything
  2. System Plumbing — Bash, Coreutils, OpenSSL, Python, Perl, and everything in between
  3. The Final Packages — SysVinit, e2fsprogs, GRUB, and system cleanup

Phase 4: Boot

Making it actually start.

  1. Bootscripts and System Configuration — SysV init scripts, network config, shell environment
  2. Compiling the Kernel — Linux 6.16.1, fstab, GRUB bootloader
  3. The Finish Line — System inventory, lessons learned, what's next

~80 packages. ~600 binaries. One kernel. Zero pre-built binaries. Built from source, obviously.
