I'm writing a bunch of tutorials for students on linux admin and stuff and it's telling how often the explanation for why something counterintuitive is like that is "Ridiculous Historical Reasons"
@kalium Explanations of the historical background behind the ridiculous reasons might make a good appendix, and would almost certainly be informative.
a unix box from back when mainframes hard drives were measured in megs had the drive mounted to / fill up
they had a second drive mounted to /usr, which at that time was for home directories, and it had space
so they started copying things that weren't required for boot from /bin and /lib and whatnot into /usr
and then users from that system began cargo culting that setup into future systems
How to explain like, four or five design decisions with one picture:
