Filesystem Hierarchy Standard
<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.
