Objective 7: Find System Files and Place Files in the Correct Location
In 1993, the Linux community formed a project to provide a standardized filesystem layout for all general-purpose distributions of Linux. The intent of this standardization was to provide advice on how to reduce the proliferation of proprietary Linux filesystem layouts and their possible contribution to market fragmentation.
The project released a document describing the Linux Filesystem Standard, usually abbreviated FSSTND, in 1994. The following year, the group began to reduce Linux-specific content and to refine the standard to include other Unix or Unix-like operating systems. As the FSSTND attracted broader appeal, it was renamed the Filesystem Hierarchy Standard. Although the FHS is not a requirement of Linux developers and distributors, the Linux community understands the importance of standards, and all major distributions support the standard.
The full FHS specification is available at http://www.pathname.com/fhs/. The information in this chapter is consistent with version 2.3 of the specification.
