Welcome to the new Linux From Scratch Blog.
The LFS and BLFS Books are designed to show you how to build a complete Linux system from source. LFS takes a user through the process of building a minimal system capable of building a more complete, but still minimal Linux system. This system forms a base from which you can choose exactly what capabilities you want.
From there, BLFS takes a different approach. It presents packages with needed prerequisites, build instructions, and minimal configuration instructions.
