What happened
Linux From Scratch (LFS) is a long-running project offering step-by-step instructions for building a custom Linux system entirely from source code. It includes subprojects like BLFS for extending the system, ALFS for automating builds, and GLFS for adding gaming support like Steam or Wine.
Why it matters
Building an OS from source is a high-yield exercise for understanding how Linux internals, dependencies, and compilation actually work, which translates directly to debugging container base images and optimizing cloud infrastructure.
Discussion angle
Whether spending a weekend building LFS is still worth it for modern developers given the abstraction layers of Docker and serverless, or if it's purely an academic exercise.
