Hey, I’ve recently designed a Poster about the FHS since I often forget where I should place or find things. Do you have any feedback how to make it better?
I updated the poster: https://whimsical.com/fhs-L6iL5t8kBtCFzAQywZyP4X use the link to see online.

What do you mean by locally vs site wide? For /usr/local that’s usually stuff installed from outside of the distributions normal packaging mechanism. E.g. if you build something from source using “make”, the “make install” would install it there by default (though that is also configurable.)
Also not sure we want to say /mnt is necessarily temporary. Any mount pionts there could easily be added to fstab.
The origin is that
/usr
may be network mounted or otherwise shared across multiple systems, whereas/usr/local
is local to a particular PC. That definition is not as relevant with today’s single-user machines, and now it mostly means what you said (/usr is managed by system package manager whereas /usr/local is manually managed).The FHS says the thing about /mnt. It’s not normally meant to have subdirectories or be mounted to by default.
