The abbreviations I wrote are unambiguous. When I first learned about Unix, I basically guessed - I assume as most first timers do - that the folder is basically the location of miscellaneous files ("et caetera").
Oh, let alone the fact that a bunch of the abbreviations are utterly non-intuitive to first timers.
/bin - binaries - nobody born after circa 1980 calls them that anymore. Executables, applications, apps, etc.
/boot - from a lame Baron Munchausen joke from 1970. Should probably be /startup.
/dev - dev is SUPER commonly used for "development". Easy enough to solve as /devices.
/home - okish, probably one of the best named that are actually in there. I'm shocked it's not /ho or /hm.
/lib - reasonable. Though these days in the US it might trigger political feelings :-p
/media - new and reasonable.
/mnt - the whole metaphor of "mounting" is... debatable.https://www.neowin.net/forum/topic/144012-unix-sex/
/opt - what does this even do? Optional? Optional WHAT? Absolutely 0 semantic info provided by the name.
Anyway, a lot of people have done this criticism better than me and it's boring at this point.
