Well done! The new CLFS system is installed! We wish you much success with your shiny new custom-built Linux system.
It may be a good idea to create an /etc/clfs-release file. By having this file, it is very easy for you (and for us if you need to ask for help at some point) to find out which CLFS version is installed on the system. Create this file by running:
echo 1.0.0rc4 > /etc/clfs-release
