## Basic filesystem types and interfaces.
##
##
##
## This module contains basic filesystem types and interfaces. This
## includes:
##
## - The concept of different file types including basic
## files, mount points, tmp files, etc.
## - Access to groups of files and all files.
## - Types and interfaces for the basic filesystem layout
## (/, /etc, /tmp, /usr, etc.).
