NAME
       filesystem - file system organization

SYNOPSIS
       /

       /usr

DESCRIPTION
       The  file system tree is organized for administrative convenience. Dis‐
       tinct 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 acces‐
       sible  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	 loca‐
       tions  for bundled software are also approved locations for add-on sys‐
       tem 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-indepen‐
       dent  file is a standard configuration file, such as /etc/hosts. Unlike
       a platform-dependent or a platform-independent file, the	 platform-spe‐
       cific  file  is installed only on a subset of supported platforms. 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 plat‐
       form-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 architec‐
       tures  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

	   a.out libraries for the Binary Compatibility Package.

       /usr/5bin

	   Symbolic link to the /usr/bin directory.

       /usr/SUNWale

	   Configuration files for Asian Lanuguage Environment (ALE).

       /usr/X11

	   Xorg Xserver (X11) executables and documentation.

       /usr/adm

	   Symbolic link to the /var/adm directory.

       /usr/apache

	   Apache executables, loadable modules, and documentation.

       /usr/appserver

	   Sun Java System Application Server software.

       /usr/aset

	   Directory for Automated Security Enhancement Tools (ASET)  programs
	   and files.

       /usr/bin

	   Platform-dependent,	user-invoked  executables.  These are commands
	   users expect to be run as part of their normal $PATH. For  executa‐
	   bles that are different on a 64-bit system than on a 32-bit system,
	   a wrapper that selects the appropriate executable is	 placed	 here.
	   See	isaexec(3C).  An  approved  installation  location for bundled
	   Solaris software. The analogous location for add-on system software
	   or for applications is /opt/packagename/bin.
