Not aware of any correct pictures, but I can tell you what’s wrong with this one
- /usr: explaining it as “Unix System Resources” is a bit vague
- /bin: /bin is usually a symlink to /usr/bin
- /sbin: /sbin is usually a symlink to /usr/sbin, distros like Fedora are also looking into merging sbin into bin
- /opt: many, I’d say most, “add-on applications” put themselves in bin
- /media: /media is usually a symlink to /run/media, also weird to mention CD-ROMs when flash drives and other forms of storage get mounted here by default
- /mnt: i would disagree about the temporary part, as I mentioned before, stuff like flash drives are usually mounted in /run/media by default
- /root: the root user is usually not enabled on home systems
- /lib: /lib is usually a symlink to /usr/lib
I would also like the mention that the FHS standard wasn’t designed to be elegant, well thought out system. It mainly documents how the filesystem has been traditionally laid out. I forget which folder(s), but once a new folder has been made just because the main hard drive in a developer’s system filled up so they created a new folder named something different on a secondary hard drive.
On my distro(Bazzite), /mnt is only a symlink to /var/mnt. Not sure why, but only found out the other day.
I’m using Silverblue and it also symlinks to /var/mnt. I don’t think it does that on traditional distros, like Fedora 40 Workstation.
