Filesystem Hierarchy Standard - Reference Poster / Cheatsheet [Dark mode in details]

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.

/home is not deprecated, it's optional but common. Here is the section from FHS: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s08.html

then the legend should be fixed its confusing, as is the whole idea of FHS is outdated and a chore for new users to get into (i still don't fully understand it)

  • difference between /media and /mnt
  • wtf is /run? some glorified /temp?
  • /usr/sbin "non vital system binaries" ... aha ok, whatever don't tell me you understand the difference between 6 (SIX !) differen bin/sbin folders
  • could continue forever...

The legend is a bit broken. Will fix it maybe.

As for the rest, yes, the FHS can be confusing. It's from a time where mostly professional admins would deal with it and requirements were pretty different from today's end-user systems. If you want to understand more, I urge you to read the spec. It's highly readable! https://refspecs.linuxfoundation.org/FHS_3.0/fhs.html

/mnt is for more permanent stuff. /run is for shit like a USB drive some user has connected. It's the place that most distro automount your attached storage by default (/run/$USER/$DEVICE/)
