Linux From Scratch 13.1: Your Own System from Source, Now with Kernel 7.1.8

The Linux From Scratch (LFS) project has unveiled version 13.1 of its book. As a reminder, LFS is not a ready-made installation image but a detailed guide that walks the reader step by step through building their own Linux system straight from source code. The project's main goal is not so much to end up with a working distribution as to understand how Linux is put together under the hood: how the individual components depend on one another and come together into a single whole.

What's New

The main changes concern the toolchain. Binutils has been updated to version 2.47, GCC to 16.2.0, and glibc to 2.44. The Linux kernel in the book has been bumped to version 7.1.8. In all, 46 packages have been updated or added since the previous release, and the total number of changes in the repository has topped 200 commits. Beyond the version changes, the authors went through the text of the book, making corrections throughout the guide.

The packages that received security updates are listed separately: attr, acl, expat, glibc, the Linux kernel, Python, systemd, util-linux, vim, and zlib. For the details on these, the project suggests looking at the Security Advisories page.

Not Just the Base System

Alongside the main book, Beyond Linux From Scratch (BLFS) is also available — an extension that explains how to install and configure additional packages on top of the base system you've built. Both books can be read online or downloaded for local use in HTML and PDF formats.

LFS traditionally sticks to a predictable release cadence, coming out twice a year, and version 13.1 continues that line, remaining one of the most instructive teaching projects in the Linux world: it answers newcomers' eternal question — why build a system by hand when there's a ready-made Debian or Fedora — by turning the build itself into a way to truly understand the operating system.
