Well done! You have finished installing your LFS system. It may have been a long process, but we hope it was worth it. We wish you a lot of fun with your new shiny custom built Linux system.
It may be a good idea to create an /etc/lfs-release file. By having this file it is very easy for you (and for us if you are going to ask for help with something at some point) to find out which LFS version you have installed on your system. Create this file by running:
echo 5.1 > /etc/lfs-release
