Filesystem Hierarchy Standard (Lesson Plan)

Definition

The Filesystem Hierarchy Standard "consists of a set of requirements and guidelines for file and directory placement under UNIX-like operating systems."

Objective

To predict the location of installed files and directories, and to place new files and directories where software expects.


Elements (simple-to-complex) (28 min)

Equipment

Errors

Application configuration cannot be in /etc.

FHS-2.3 reserves /etc for "system configuration". Application configuration should be in /etc/opt/<package>. Note that this deprecates FHS-2.2 usage by farms.

X11 files should be under /[etc usr]/X11.

Because of historic usage, FHS-2.3 specifically exempts X11 from the requirement to reside under /opt.
