Oh, in that case, and considering the list of devices you’re updating, you might be interested in putting Linux From Scratch on one of the disposable devices:
I wouldn’t run it as my main driver, but it’s a book that steps you through each package to manually compile until you have a fully working system. It’s pretty error prone but along the way you learn how most of the pieces fit together. It’s probably still a bit much for now but I thought I’d mention it
