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.

Damn that’s some great work ! When I started linux I wish I had found such ressources, I was really curious what each of these directories were for.
Would you mind if your material was reused (with credit) for education purposes ?
The FHS was started in 1994 and is free to use. It should be used now by all major Linux systems and most Unix too.
The only credit is to the Linux Foundation.
But $vendor, which supplies $application, doesn’t give a flying fuck about this. I’ve seen binaries in /etc/opt/$application or something like that.
Tell them. Many people don’t know about FHS. Seriously, just the person I was answering to was giving credit to some rando who copy pasted an image from the Linux foundation.
I’ve been educating people on this all my professional life. I try to make a change with the people around me, but I’ve also filed big to some FOSS projects that got it wrong. Some did the change, some were unwilling. But it’s unknown if even those did follow the right convention in their next project.

I just mount mine into /mnt and bind mount subdirectories from them into wherever I need the space.
Edit: if you want a more theoretically correct location according to the FHS you could mount drives somewhere under /run and bind their contents from there. I’ve done that before as well.
tbh I don’t think it matters, so wherever you feel like doing it. I just leave it where the distro or file manager defaults to: in Ubuntu-based distros that’s /media/$USER/mount-name
. For mounts shared across users you could drop the .
Since FHS doesn’t specify where “non-removable media” should go, I don’t think it makes sense to adopt this recommendation as /media
should be removable, but rather, “in case the media IS removable, then mount it to /media/
”.
If they are internal and permanent (read: unlikely to be removed on a daily basis), I’d just mount them based on their purpose and not them being separate HDDs physically. If they are meant for logs, mount them at /var/log. If they are meant for your movies, /home/user/data is more than fine. In general FHS describes the directory hierarchy, not which parts of it are mountpoints and which are physically on the same media. Technically you’re fine having each and every directory on a separate HDD.
I’m also mounting them into /home/user/data while I don’t think hard-coding the user name in the mountpoint is a good idea. Besides, it needs the assumption that I’m the only “human-user” of this computer.
I may also mount them at /opt/data, but I’m not sure if it’s a good idea
I originally had mine mounted on /
, to make them easy to type. But that set one of my highly opinionated friends wretching, so I re-mounted them to /media//
to placate him and symlinked them to my home directory instead.
It’s frustrating how often Linux systems, when approached with a “where is the canonical location for ?” question, have an answer ancient use cases practically no one has anymore, but no satisfying answer for extremely common use cases like permanently mounted backup drives, where to put web server hosted files, or even where to install applications that don’t come from package managers (/
? //usr/bin/
? /home//.local/
?).
I’m coming more from a server perspective but, fundamentally, all HDDs are “temporary”. Eventually that data might be in a bigger/faster/functioning replacement - so it’s best to treat the drive as something which can always be replaced.
Continuing that, you might mount to /mnt and then symlink that where you really want it, say …/games. That layer of abstraction allows you to replace the drive without much effect on install. Also allows for expansion via something like mergerfs (*no idea if that’s a good idea for your use cases)
/mnt is explicitly meant to be used as temporary mountpoint for admins. That’s not a good place.
I’m still learning myself, but I think in a good number of uses cases it qualifies. There are two parts of that explicit definition which seem important, “temporary” and “non-installation”. “Temporary” is the most ambiguous. An array of JBoD storing media files, which can be unplugged really at any time without affecting any system, meets that definition. Game installs or the operating system, less so. I totally get my specific usage may not lend to generic advice. In the interest of me learning, here’s where I started (which advises /mnt): https://perfectmediaserver.com/02-tech-stack/mergerfs/
