Actually LFS teaches you about the whole GNU Userland, getting a kernel up and running with busybox is much easier. This project does just that - teaching you the bare minimum.

The embedded version of CLFS (Cross-Compiled Linux From Scratch) covers building a musl + busybox system: http://clfs.org/view/clfs-embedded/x86/
But the more resources available on this kind of thing the better IMHO, there's not really a one size fits all :)
