i once sat down to go through this as a challenge, but started to get bored quickly. skipping ahead, i built bash, configured grub to init=/bin/bash, threw in coreutils, and was very thrilled to see my very own "distro" boot in under a second (not counting bios init ofcourse) on an ancient p3 box. i think i disabled everything i could think of in the kernel (including filesystem support, which was quickly rectified) for a truly 'minimalist' experience. it ofcourse didnt do much but it was very responsive.

  Same here, I tried it on a 486 and it became an idle game. Just glancing on it from time to time, lines are still running down the screen, OK, move on to other things. u-root is mentioned in the article -- I used buildroot and busybox for embedded Linux development while in university: https://buildroot.org/ https://buildroot.org/

LFS takes the opposite approach. You build a cross compilation toolchain, build out a full Linux file system, compile a massive number of packages… it’s almost two days of work before you even start thinking about a boot loader. This tutorial gets straight to the heart of the matter. Get a system that boots asap and then add complexity as you discover the shortcomings. This seems like a much better pedagogical approach for someone not sure how the kernel works or what initramfs is, etc…

LFS has been on my todo list for like a decade, I really need to plan a weekend and just do it

  I did it once, about twelve years ago, just to prove to myself that I could. It was kind of fun, but I have absolutely no desire to do it again. I tried running it as my "full time" distro but what I ended up with was something extremely fragile and decidedly not fun for me to use. Nowadays I run a NixOS Minimal install, which is about the level of operating system that I like to work in.

  I think it's a month thing rather than a weekend thing, no?

    Depends on your CPU (due to all the compiling), and if you plan on only doing the base OS or the extended plans too.
