FHS 2.1 is done!

I’m pleased to announce the release of FHS 2.1, a updated
version of the Filesystem Hierarchy Standard for Linux and other
Unix-like operating systems. FHS is part of the draft Linux
Standard Base specification, which will soon be updated to reflect
FHS 2.1.

FHS 2.1 supersedes both FSSTND 1.2 and FHS 2.0. There have been
some significant improvements and bug fixes since FHS 2.0. Please
see the FHS web site for details. (It has been a few years since
the last official release, so check it out if you’re using a
previous version of FHS or FSSTND.)

What is FHS?

FHS defines a common arrangement of the many files and
directories in Unix-like systems (the filesystem hierarchy) that
many different developers and groups have agreed to use. See below
for details on retrieving the standard.

The FHS specification is used by the implementors of Linux
distributions and other Unix-like operating systems, application
developers, and open-source writers. In addition, many system
administrators and users have found it to be a useful resource.

FHS or its predecessor, FSSTND, is currently implemented by most
major Linux distributions, including Debian, Red Hat, Caldera,
SuSE, and more.
