This version of the book has undergone a major reorganization. It uses enhanced cross-compilation techniques and an environment isolated from the host system to build tools for the final system. This reduces both the chance for changing the the host system and the potential of the host system influencing the LFS build process.
Major package updates include toolchain versions glibc-2.32, gccc-10.2.0, and binutils-2.35. In total, 37 packages were updated since the last release. The Linux kernel has also been updated to version 5.8.3.
There’s a separate version for systemd – for those so inclined.
