According to the Linux From Scratch website, Linux From Scratch (LFS) is a project that supplies step‑by‑step instructions for constructing a custom Linux system entirely from source code. The site explains that the organization currently consists of a set of subprojects, each serving a different purpose in the LFS ecosystem. The core LFS book forms the foundation, providing the basic process for building a minimal Linux system. Beyond Linux From Scratch (BLFS) extends that foundation, helping users add additional software and configurations to create a more functional and personalized system. For those who wish to streamline the build process, Automated Linux From Scratch (ALFS) offers tools designed to automate and manage both LFS and BLFS compilations. Multilib Linux From Scratch (MLFS) is a variant that enables the resulting system to compile and run 32‑bit binaries alongside the native 64‑bit environment. Gaming Linux From Scratch (GLFS), based on BLFS, focuses on installing gaming‑related software such as Steam or Wine on a fresh LFS or MLFS installation. Supplemental Linux From Scratch (SLFS) provides further additions that go beyond the scope of BLFS. The Hints project collects documents that describe enhancements not covered in the main LFS or BLFS books, while the Patches project maintains a central repository of patches useful to LFS users. Additional resources include the LFS Editor’s Guide, which outlines the development process for the main book, and the Museum, which archives older versions of LFS and BLFS for reference. All of these components are presented as part of a single, coordinated effort to enable users to build, modify, and maintain a Linux system from the ground up.
