Here is an example of using Ignite-UX post-installation scripts
to load software on new installs. Netscape is one of those tools
which seems to have a new version every six months. Due to the frequency
of the changes, this tool may not make sense to include on the "golden
system".
This example shows one way of accomplishing the task using
a post_config_script. Another way would be to create a software selection
(sw_sel) that would reference the tar archive, and then
a post_config_script (or post_config_cmd) associated with the sw_sel that would be run only if the selection was picked
for loading. Using a sw_sel would have the advantage of making it appear in
the UI as just another software selection, and would have the sw_impact statements to ensure sufficient file system space.
For more examples, see the files in /opt/ignite/data/examples.

Get Netscape Navigator — Netscape
Navigator is typically pulled from one of the Netscape ftp server
sites. The pulled files are gzip compressed tar images with an encoded
name similar to:
netscape-v30-export.hppa1.1-hp-hpux.tar.gz
Special Considerations for Netscape — In order
to run Navigator, each user needs the correct network preferences.
Unfortunately, these preferences cannot be defaulted, and must exist
in every users $HOME/.netscape directory. To get around this limitation, we have supplied
a "run-netscape" script. Instead of running "netscape",
the user can run a link to "run-netscape" which
will install the default preferences at first invocation.
A sample "run-netscape" script is shown
below. You will also need to create a default configuration file.
Merely take an existing one and remove all user and host specific
information.
Write an install and customization script — Attached
below is a script we used for installing Netscape in our environment.
The script does the following:
Remote copies from a server to the
local target netscape, a default-preferences file, and the special
run-netscape script.
Unpacks Netscape.
Makes /usr/local/bin/netscape a link to "run-netscape" to ensure user
defaults will be installed.
Performs the special netscape customization.
Cleans up.
We named and placed our script under:
/var/opt/ignite/scripts/install_netscape
Add the install script to Ignite-UX customization — Add
a line like this to one of your config files (not in a clause):
post_config_script="/var/opt/ignite/scripts/install_netscape"
For details of adding a post configuration script, see Chapter
9. This script will need to be accessible using tftp.
Example script
Here's an example post-install script for Netscape:
# !/usr/bin/ksh
#
# Post Ignite-UX installation script used to install Netscape
version 3.0.
# This installation assumes HP-UX 11.00 because it
depends on gzip
# already loaded on the system.

Example run time script for Netscape
