Just before LinuxCon North America in Vancouver, The Linux Foundation released a draft proposal for an update to the Filesystem Hierarchy Standard (FHS). Versions of the draft (in text mode, HTML, and PDF) can be found at
This draft removes quite a few historical artifacts, such as /usr/X11R6 and subdirectories in /usr/bin, and adds many recent developments, including /sys and /run.
Draft 1 is aimed at getting the normative text of the standard out there for review; thus, a number of issues with formatting, editorial statements, and references are still missing. Nonetheless, this draft accurately reflects the restrictions and obligations that will likely be a part of FHS 3.0 in the end. In other words: now is the time to review!
