Using Configuration Files
Introduction
Introduction
The Ignite-UX central data store is called a config file. A config file can be
thought of as a recipe for how to construct a target system. The config file
is expressed in a language designed for this purpose. The language is
fully defined in the instl_adm(4) manual page. The syntax is
human-readable; config files may be created directly by a user or via the
Ignite-UX graphical user interface. The config file language is much like
many programming languages in that it supports the use of variables
and conditional expressions.
Most of the important elements which make up an installed system can
be described in the config file, as follows:
• Disk and file system layout.
• Software to be installed.
• The target system hardware identity and network configuration.
• Kernel modifications (additional drivers or tunable parameter
• User-defined scripts which will run at various points in the
Types of Config Files For maintenance convenience, the configuration information is split into
several different config files. These config files fall into the following
basic classes:
• Default disk and file system layout.
• Software description of a single SD depot.

settings).
installation process to further customize the target machine.
Because the capabilities of each operating system release differ
somewhat, HP supplies a different set of defaults for each release.
These are located in /opt/ignite/data/ Rel_release/config,
where release is the result of the uname -r command. For example,
/opt/ignite/data/Rel_B.10.20/config contains the default
disk layouts for the HP-UX 10.20 release.
