NAME
filesystem - File system organization
SYNOPSIS
/ /usrDESCRIPTION
The file system tree is organized for administrative con-
venience. Distinct areas within the file system tree are provided for files that are private to one machine, filesthat can be shared by multiple machines of a common plat-
form, 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 /usrfile 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 alsoapproved locations for add-on system software or for appli-
cations. The following descriptions make clear where the two locations differ. For example, /etc is the installationlocation 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)SunOS 5.11 Last change: 14 Jul 2010 1

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 plat-
form. Like a platform-dependent file, a platform-independent
file is installed on all platforms. However, the contents ofthe latter type remains the same on all platforms. An exam-
ple 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 aplatform-dependent or a platform-independent file, the
platform-specific file is installed only on a subset of sup-
ported 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. Root File System The root file system contains files that are unique to each machine. It contains the following directories: / Root of the overall file system name space. /dev Primary location for special files. Typically, devicefiles are built to match the kernel and hardware confi-
guration of the machine. /dev/cfgSymbolic links to physical ap_ids.

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 sharemany different /usr file systems to support several dif-
ferent architectures and operating system releases. Clientsusually mount /usr read-only so that they do not acciden-
tally change any shared files. The /usr file system contains the following subdirectories:SunOS 5.11 Last change: 14 Jul 2010 21

/usr/lib/sysevent Contains the system event notification daemon (syseventd) and the syseventd loadable module (SLM) repository. /usr/lib/uucp Auxiliary programs and daemons for uucp(1C). /usr/lib/webconsole Sun Java web console programs and scripts. /usr/lib/zones Zone administration daemon (zoneamd). /usr/localNot part of the SVR4-based Solaris distribution. The
/usr directory is exclusively for software bundled with the Solaris operating system. If needed for storingmachine-local add-on software, create the directory
/opt/local and make /usr/local a symbolic link to/opt/local. The /opt directory or filesystem is for
storing add-on software to the system.
