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 \

/var/uucp

uucp(1C) log and status files.

/var/yp

/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.
