Linux From Scratch (LFS) offers detailed guidance on creating your own Linux system from scratch using source code. The project includes various subprojects such as LFS (the main book), BLFS (for customization), ALFS (automation tools), Hints (additional enhancements), Patches (repository for useful patches), and the LFS Editor’s Guide. Surprisingly, they also have a Museum section dedicated to preserving ancient versions of LFS and BLFS. Users can follow the step-by-step instructions provided to build a unique and personalized Linux system tailored to their needs.
