+ About the Cross Edition
+
+ While LFS has provided an approach to build a Linux system entirely
+ from source code, it builds the LFS system in a
+ chroot environment. The chroot environment is almost
+ seperate from the host distribution, but it still relies on the hardware
+ and Linux kernel from the host system.
+
+ The Cross Edition contains modification to the LFS book, allowing
+ to boot the temporary system instead of chroot. So it's possible to
+ bootstrap a Linux system for a target where no Linux distribution exists.
+ And, the kernel ABI may frequently change at the early stage porting Linux
+ to a new hardware. The modification in this edition completely removes
+ the dependency on the kernel from the host distribution, allowing to
+ rebuild the entire system with a new kernel ABI.
+
+ If you already have a Linux distribution running on the hardware
+ where you need a Linux From Scratch system, with the kernel ABI you want,
+ and it's compatible with the Host System Requirements specified by the
+ LFS book, it's likely you should read the original LFS book instead of
+ this edition.
+
+ This edition contains instructions to bootstrap a Linux system for
+ x86 (32-bit or 64-bit). It may looks irrational because it's easy to
+ find a host distribution for x86, but this edition can be a start point
+ where you can further modify the instruction for other hardware.
+
+
+ History of Cross LFS
+
+ A project named Cross Linux From Scratch
+ was forked from LFS in 2006, by Joe Ciccone, Jim Gifford, and
+ Ryan Oliver. It has been inactive since 2017. Its history can still
+ be explored at .
+
+ In 2020, Pierre Labastie modified the LFS book to cross-compile
+ the temporary packages before entering the chroot environment. The main
+ purpose of this approach was to fix multiple issues found by Iterative
+ Comparision Analysis. With Pierre's work, the only change needed by
+ this edition is basically to reboot instead of chroot
.
+ However, some additional steps is needed to make the system bootable
+ at the end of Chapter 6, and setting up an environment suitable for
+ building and test packages at the start of Chapter 7. Then this Cross
+ Edition is created to demonstrate these steps.
