Adding to the array of software projects and specifications under the FreeDesktop.org umbrella, the Filesystem Hierarchy Standard "FHS" has been adopted by these desktop-focused open-source developers.

The Filesystem Hierarchy Standard is the standard around file/directory placement on Linux and Unix-like systems. Prominent open-source developer Matthias Klumpp announced today that the Filesystem Hierarchy Standard has been adopted by FreeDesktop.org. For the moment the FHS version is still 3.0, which was released a decade ago (May 2015).

Klumpp acknowledged in the announcement of adopting the FHS that it's "historically interesting" but in the future they hope this will lead to improvements/modernization.

The FHS specification can be found at specifications.freedesktop.org/fhs. The FHS specification itself is managed via this FreeDesktop.org GitLab repository for any modernization improvements and additions moving forward.
