I have learned of Linux from Scratch. I love the idea of it. I have sunk my teeth into learning a bit about it. I have dabbled; but never made huge progress on it.
Oh absolutely, Arch was my entry way to a deeper understanding. While I can and do compile packages myself, and pick and choose different parts of my system; it isn't the same as doing it from scratch.
I have tried a few Atomic Distros, and they just aren't my thing. Even my steam deck I switched to cachyos because I didn't want to change my behavior in how I interact with my OS.
Luckily as far as something just working; my Arch install is set and forget. I just update regularly and everything continues to work. I have not had to troubleshoot really anything.
For my usecase, I am running Arch with Limine on a luks encrypted btrfs drive with snapper and tools to sync snapshots to limine. Add in a few other tweaks, probably more I have forgotten about. And I have my perfect system.
But eventually I will delve further into LFS.
And that is just my desktop. I also have a separate arch install for my laptop. Then I have multiple servers I run various distros on. Fedora Server, Raspberry Pi OS. And I even have a test machine I use to test drive other distros and use to install packages I want to test before implementing into my current system.
