LFS provides a fantastic learning experience that I wish I had undertaken many years ago. Although the documentation may seem unassuming at first glance, it is crucial to thoroughly read and comprehend it.

At first, it might appear somewhat futile, but the process teaches you the essential components of a Linux system and how to construct them from the ground up. Despite its repetitive nature, the exercise helps you master shell commands and procedures. Repeating the process multiple times is highly beneficial.

Key considerations:

• Create a live USB drive with Gentoo or Slackware.
• Boot from the USB drive.
• Utilize an older device, such as a laptop, for LFS experiments.
• Follow the LFS documentation meticulously; every aspect is covered within it. Mistakes only arise from neglecting to read the documentation. RTFM!
• Download and install wget and openssh, as they are not part of the LFS but significantly enhance your future experiences.
• Repeat the process several times.
• Whenever possible (except in some cases - RTFM), compile using ‘make -jx,’ where x represents the number of CPUs, as it dramatically reduces processing time.
• Building a custom kernel is enjoyable, although it can be prone to errors and time-consuming. Always backup before updating the kernel on a working system.
• Never upgrade your working kernel! It is the best advice ever. Despite the controversy, this precaution is advisable, as outlined in the Slackware documentation.
• Gentoo serves as a lighter alternative to LFS with fewer steps and an excellent overall experience. Some aspects of Gentoo’s documentation surpass others.
• While not suitable as a primary desktop system due to the extensive work required for updates, Gentoo and LFS make outstanding training systems.
