NAME
clustertoc - cluster table of contents description file
The cluster table of contents file, .clustertoc, is an ASCII file that describes a hierarchical view of a software product. A .clustertoc
file is required for the base OS product. The file resides in the top-level directory containing the product.
The hierarchy described by .clustertoc can be of arbitrary depth, although the initial system installation programs assume that it has
three levels. The hierarchy is described bottom-up, with the packages described in .packagetoc at the lowest layer. The next layer is the
cluster layer which collects packages into functional units. The highest layer is the meta-cluster layer which collects packages and clus-
ters together into typical configurations.
The hierarchy exists to facilitate the selection or deselection of software for installation at varying levels of granularity. Interacting
at the package level gives the finest level of control over what software is to be installed.
Each entry in the .clustertoc file is a line that establishes the value of a parameter in the following form:
PARAM=value
A line starting with a pound-sign, ``#'', is considered a comment and is ignored.
Parameters are grouped by cluster or meta-cluster. The start of a cluster description is defined by a line of the form:
CLUSTER=value
The start of a meta-cluster description is defined by a line of the form:
METACLUSTER=value
There is no order implied or assumed for specifying the parameters for a (meta-)cluster with the exception of the CLUSTER or METACLUSTER
parameter, which must appear first and the END parameter which must appear last.
The following parameters are mandatory:
CLUSTER
The cluster identifier (for example, SUNWCacc). The identifier specified must be unique within the package and cluster identifier
namespace defined by a product's .packagetoc and .clustertoc files. The identifiers used are subject to the same constraints as those
for package identifiers. These constraints are (from pkginfo(4)):
All characters in the abbreviation must be alphanumeric and the first may not be numeric. The abbreviation is limited to a maximum
length of nine characters. install, new, and all are reserved abbreviations.
A cluster must be described before another cluster or meta-cluster may refer to it.
DESC
An informative textual description of the (meta-)cluster's contents. The length of the description supplied may not exceed 256 charac-
ters. The text should contain no newlines.
METACLUSTER
The metacluster identifier (for example, SUNWCprog). The identifier specified must be unique within the package and cluster identifier
namespace defined by a product's .packagetoc and .clustertoc files. The identifiers used are subject to the same constraints as those
for package identifiers. These constraints are (from pkginfo(4)):
All characters in the abbreviation must be alphanumeric and the first may not be numeric. The abbreviation is limited to a maximum
length of nine characters. install, new, and all are reserved abbreviations.
Meta-clusters can not contain references to other meta-clusters.
NAME
The full name of the (meta-)cluster. The length of the name string supplied may not exceed 256 characters.
SUNW_CSRMEMBER
Indicates that the package or cluster is a part of the (meta-) cluster currently being described. The value specified is the identifier
of the package or cluster. There may be an arbitrary number of SUNW_CSRMEMBER parameters per (meta-)cluster.
VENDOR
The name of the (meta-)cluster's vendor. The length of the vendor string supplied may not exceed 256 characters.
VERSION
The version of the (meta-)cluster. The length of the version string supplied may not exceed 256 characters.
The following parameters are optional:
DEFAULT
Specifies which metacluster within a .clustertoc file should be selected or installed by default. Only one metacluster can be the
default.
HIDDEN
Specifies whether a metacluster should be hidden by applications. A hidden metacluster cannot be DEFAULT.
REQUIRED
Specifies which metacluster is required. A required metacluster implies that all of its cluster and package members are not de-
selectable (must be installed).
SUNW_CSRMBRIFF
Indicates that the package is to be included dynamically in the (meta-)cluster currently being described. The value of this parameter
must follow the following format:
SUNW_CSRMBRIFF=(test test_arc)package
This line is converted into a SUNW_CSRMEMBER entry at media installation time if the test provided matches the platform on which the
media is being installed. There may be zero or more SUNW_CSRMBRIFF parameters per (meta-)cluster.
SUNW_CSRMBRIFF=(test value)package
where the test is either the builtin test of "platform" or a shell script which returns shell true(0) or shell false(1) depending on
the tests being performed in the script. value is passed to the test as the first argument and can be used to create a script that
tests for multiple hardware objects. Finally package is the package that is included in the final .clustertoc file as a SUNW_CSRMEMBER.
See parse_dynamic_clustertoc(1M) for more information about the scripts.

eter entries.

typical software used by software developers.

The current implementation of the initial system installation programs depend on the .clustertoc describing three required meta-clusters
for the base OS product:
SUNWCall Contains all of the software packages in the OS distribution.
SUNWCuser Contains the typical software packages for an end-user of the OS distribution.
SUNWCreq Contains the bare-minimum packages required to boot and configure the OS to the point of running a multi-user shell.
