I completely agree! If you're looking to deeply understand how Linux works under the hood, I highly recommend trying out Linux From Scratch. It gave me invaluable insight into the system, especially when I first explored it 20 years ago. Building everything from the ground up—without relying on prepackaged distros or libc—was a game changer.

I ran through that about 10 years ago. Not difficult for a reasonably seasoned Unixy person to run through but it quite frankly scared the shit out of me on the basis of how much stuff requires patching and hacking. Nothing fits together nicely. It gave me a whole new appreciation of macOS and FreeBSD.
