NAME
filesystem - file system organization

SYNOPSIS
/

/usr

The file system tree is organized for administrative convenience. Distinct areas within the file system tree are provided for files that
are private to one machine, files that can be shared by multiple machines of a common platform, files that can be shared by all machines,
and home directories. This organization allows sharable files to be stored on one machine but accessed by many machines using a remote
file access mechanism such as NFS. Grouping together similar files makes the file system tree easier to upgrade and manage.

The file system tree consists of a root file system and a collection of mountable file systems. The mount(2) program attaches mountable
file systems to the file system tree at mount points (directory entries) in the root file system or other previously mounted file systems.
Two file systems, / (the root) and /usr, must be mounted and /var must be accessible to have a functional system. The root file system is
mounted automatically by the kernel at boot time; the /usr file system is mounted by the system start-up script, which is run as part of
the booting process. /var can be mounted as its own file system or be part of /usr, as it is by default.

Certain locations, noted below, are approved installation locations for bundled Foundation Solaris software. In some cases, the approved
locations for bundled software are also approved locations for add-on system software or for applications. The following descriptions make
clear where the two locations differ. For example, /etc is the installation location for platform-dependent configuration files that are
bundled with Solaris software. The analogous location for applications is /etc/opt/packagename.

In the following descriptions, subsystem is a category of application or system software, such as a window system (dt) or a language
(java1.2)

The following descriptions make use of the terms platform, platform-dependent, platform-independent, and platform-specific. Platform refers
to a machines Instruction Set Architecture or processor type, such as is returned by uname -i. Platform-dependent refers to a file that is
installed on all platforms and whose contents vary depending on the platform. Like a platform-dependent file, a platform-independent file
is installed on all platforms. However, the contents of the latter type remains the same on all platforms. An example of a platform-depen-
dent file is compiled, executable program. An example of a platform-independent file is a standard configuration file, such as /etc/hosts.
Unlike a platform-dependent or a platform-independent file, the platform-specific file is installed only on a subset of supported plat-
forms. Most platform-specific files are gathered under /platform and /usr/platform.

In the following file or directory descriptions, GNOME stands for GNU Network Object Model Environment. The GNOME Desktop is shipped with
the Solaris operating system.

/usr File System
Because it is desirable to keep the root file system small and not volatile, on disk-based systems larger file systems are often mounted on
/home, /opt, /usr, and /var.

The file system mounted on /usr contains platform-dependent and platform-independent sharable files. The subtree rooted at /usr/share con-
tains platform-independent sharable files; the rest of the /usr tree contains platform-dependent files. By mounting a common remote file
system, a group of machines with a common platform may share a single /usr file system. A single /usr/share file system can be shared by
machines of any platform. A machine acting as a file server can share many different /usr file systems to support several different archi-
tectures and operating system releases. Clients usually mount /usr read-only so that they do not accidentally change any shared files.

The /usr file system contains the following subdirectories:

/usr/4lib
