LFS Commands is a tarball containing files which list the installation commands for the packages installed in this book. These files can be used to dump to your shell and install the packages, though some files need to be modified (for example when you install the console-tools package you need to select your keyboard layout file which can't be guessed).
These files can be used to quickly find out which commands have been changed between the different LFS versions as well. You can download the lfs-commands tarball for this book version and the previous book version and run a diff on the files. That way you can see which package have updated installation instructions so you can modify your own scripts, or reinstall a package if you deem necessary.
The lfscommands can be downloaded from http://download.linuxfromscratch.org/lfs-commands/ or ftp://download.linuxfromscratch.org/lfs-commands/
