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.

/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 contains 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
architectures 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/5bin
Symbolic link to the /usr/bin directory.
/usr/X11
Xorg Xserver (X11) executables and documentation.

applications is
