From the “Prerequisites” section of LFS:
Building an LFS system is not a simple task. It requires a certain level of existing knowledge of Unix system administration in order to resolve problems and correctly execute the commands listed. In particular, as an absolute minimum, you should already know how to use the command line (shell) to copy or move files and directories, list directory and file contents, and change the current directory. It is also expected that you know how to use and install Linux software.
Did you? You’re suggesting that someone who wants to learn how to maintain a car build one from scratch. It’s drastically overshooting the assignment.
