Linux from Scratch
An open-source project for advanced users that provides a complete step-by-step guide for manually compiling and building a customized Linux system from source code. It is accompanied by supplementary books including BLFS and ALFS, and serves as a reference resource for learning Linux internals.

Linux from Scratch (LFS) is an open-source project that provides a complete step-by-step guide teaching users to manually compile and build a Linux system entirely from source code.
LFS recently received 267 upvotes and 79 comments on Hacker News.
The toolchain bootstrapping mechanism in LFS works by first using the host machine's compiler to build a temporary compilation environment, then using that temporary environment to compile the final system, thereby eliminating dependency on the host machine.
In the LFS build process, the chroot command is used to switch the root directory, simulating a target environment isolated from the host machine.
The LFS core manual covers approximately 80-plus software packages.
The LFS project provides versions targeting different hardware architectures and offers documentation in multiple language translations.
LFS is not suitable for beginners looking to get started with Linux quickly; it requires patience, a command-line foundation, and the ability to troubleshoot compilation errors.
ALFS assumes that users already understand every step of the manual build process and is not suitable as a replacement for the LFS manual as a beginner learning path.
