NAME

filesystem - File system organization

SYNOPSIS

/

/usr

DESCRIPTION

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-dependent 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 platforms. Most platform-specific files are gathered under
/platform and /usr/platform.

It is possible to change the default behavior for /var/tmp to
clear all of the files except editor temporary files by setting
the clean_vartmp property value of the rmtmpfiles service. This
is done with the following commands:

# svccfg -s svc:/system/rmtmpfiles setprop \

/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.
