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 a shell and install the packages, though some files need to be modified (for example, when the kbd package is installed, you needed to select the keyboard layout file, becaue it can't reliably be guessed).
These files can also be used to quickly find out which commands have been changed between the different LFS versions as well. Download the lfs-commands tarball for this book version and the previous book version and run a diff on the files. That way it is possible to see which packages have updated installation instructions, so any scripts you may have can be modified, or you can reinstall a package if you think that necessary.
The lfscommands can be downloaded from http://packages.linuxfromscratch.org/lfs-commands/ or ftp://packages.linuxfromscratch.org/lfs-commands/.
