This page is the home of the Filesystem Hierarchy Standard (FHS). The current version is 2.3. It was announced on January 29, 2004.
The filesystem standard has been designed to be used by Unix distribution developers, package developers, and system implementors. However, it is primarily intended to be a reference and is not a tutorial on how to manage a Unix filesystem or directory hierarchy.
The official home for the FHS specification at the Linux Foundation is at our Reference Specifications site.
The mailing list is available to discuss interpretations of the FHS document and of possible future changes and additions.
All proposals should be submitted as bugs on bugs.linux-foundation.org using the "FHS" component). Please include a unified patch or Bazaar bundled revision to the SGML source, either the last released version or the current in-progress version, when proposing a change in the bug tracker (create the attachment after you've opened the bug; please do not cut-and-paste patches into comments).
