Filesystem Hierarchy Standard
FHS

   <storage, standard> (FHS) A {standard} designed to be used by
   {Unix} {distribution} developers, {package} developers, and
   system implementors.

   FHS consists of a set of {requirements} and guidelines for
   file and directory placement under {UNIX}-like {operating
   systems}.

   The {guidelines} are intended to support interoperability of
   applications, system administration tools, development tools,
   and scripts.  These systems should also be supported with
   greater documentation uniformity.

   The standard is primarily intended to be a reference and is
   not a tutorial on how to manage a Unix filesystem or directory
   hierarchy.
