NAME

clustertoc- cluster table of contents description file

DESCRIPTION

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 clusters 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.

Each parameter is described below. All of the 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.

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)):

Meta-clusters cannot 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.

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.

DESC

An informative textual description of the (meta-)cluster's contents. The length of the description supplied may not exceed 256 characters. The text should contain no newlines.

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.

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 will be 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 SUN_CSRMBRIFF parameters per (meta-)cluster.

SUNW_CSRMBRIFF=(<test> <value>)<package>

where the 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 will be included in the final .clustertoc file as a SUNW_CSRMEMBER. See parse_dynamic_clustertoc(1M) for more information about the scripts.

EXAMPLES

Example 1 A Cluster Description

The following is an example of a cluster description in a .clustertoc file.

CLUSTER=SUNWCacc
NAME=System Accounting
DESC=System accounting utilities
VENDOR=Sun Microsystems, Inc.
VERSION=7.2
SUNW_CSRMEMBER=SUNWaccr
SUNW_CSRMEMBER=SUNWaccu
END

Example 2 A Meta-cluster Description

The following is an example of a meta-cluster description in a .clustertoc file.

METACLUSTER=SUNWCreq
NAME=Core System Support
DESC=A pre-defined software configuration consisting of the minimum
required software for a standalone, non-networked workstation.
VENDOR=Sun Microsystems, Inc.
VERSION=2.x
SUNW_CSRMEMBER=SUNWadmr
SUNW_CSRMEMBER=SUNWcar
SUNW_CSRMEMBER=SUNWCcs
SUNW_CSRMEMBER=SUNWCcg6
SUNW_CSRMEMBER=SUNWCdfb
SUNW_CSRMEMBER=SUNWkvm
SUNW_CSRMEMBER=SUNWCnis
SUNW_CSRMEMBER=SUNWowdv
SUNW_CSRMEMBER=SUNWter
END

Example 3 A Meta-cluster Description With a Dynamic Cluster Entry

The following is an example of a meta-cluster description with a dynamic cluster entry as indicated by the use of the SUNW_CSRMBRIFF parameter entries.

METACLUSTER=SUNWCprog
NAME=Developer System Support
DESC=A pre-defined software configuration consisting of the
typical software used by software developers.
VENDOR=Sun Microsystems, Inc.
VERSION=2.5
SUNW_CSRMEMBER=SUNWCadm
SUNW_CSRMBRIFF=(smcc.dctoc tcx)SUNWCtcx
SUNW_CSRMBRIFF=(smcc.dctoc leo)SUNWCleo
SUNW_CSRMBRIFF=(smcc.dctoc sx)SUNWCsx
 . . .
END

NOTES

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.
