So many good memories I had running through this way back when and it gave such a good and deep look into how a fully functioning system worked. It removed a lot of the mystery of this distro vs that distro and how all the pieces fit together. I still use some of the knowledge I gained from this in my day-to-day work, some of which is sorely lacking by others doing seemingly the same job as me.

I remember going through this and there was a point where you were running a stock, generic kernel before having built a specialized kernel with modules and options you wanted. I apparently ran up against thermal limits on this laptop because power management was one of the options for you to configure. I had to zoom through that section with a box fan pointed at that laptop so I could get power management and throttling to work so it wouldn't randomly shut down. Good times.

I used the same laptop I went through the first time with the same LFS install for a number of years after that until my day job killed my interest in doing this stuff in my free time. I switched to Debian after that and never looked back.

Like others are saying, I always recommend going through this for those that want a deeper understanding of linux, the kernel, and all its accoutrements.
