This repository is a practical, checkpoint-driven guide for building Linux From Scratch (arm64-r13.0-74, systemd edition) on Apple Silicon.

Reference book: https://www.linuxfromscratch.org/~xry111/lfs/view/arm64-systemd/

• Real host target: Apple Silicon + VMware + Debian ARM64.
• Step-by-step structure by phases, not giant walls of text.
• Verification points to catch failures early.
• Written for repeatability and team sharing.

pie title Relative Build Effort
  "Setup + Host Prep" : 10
  "Environment + Sources" : 10
  "Cross Toolchain" : 30
  "Chroot Entry" : 5
  "System Packages" : 30
  "Boot + Kernel + GRUB" : 15

• Requirements and VMware Setup
• Host System Verification
• Disk Partitioning and Mounting

• LFS User and Environment
• Source Downloads, Checksums, FHS Layout

• Bootstrap Overview
• Binutils Pass 1
• GCC Pass 1
• Kernel Headers and Glibc
• Libstdc++ and Binutils Pass 2
• GCC Pass 2

• Entering Chroot and Initial Setup

• Temporary Tools
• Core Libraries
• GCC Final, System Utilities, Systemd
• Remaining Packages

• System Configuration
• Kernel Compilation
• GRUB Setup
• First Boot Verification

• Pitfalls and Fixes
• Host Verification Script

• Use make -j$(nproc) unless a step says otherwise.
• Remove each source directory after install.
• Export LFS=/mnt/lfs in every relevant shell.
• Run cross-toolchain steps as lfs, and full system steps as root inside chroot.
• Do not skip verification commands; they prevent multi-day rework.
