HP Insight Control for Linux 6.2 User Guide

3. Create the following scripts, as needed:
DescriptionScript
Required for an unattended installation, this script performs macro substitution
so that a working copy of your installation configuration file has the actual
values required for your installation.
auto_config
This script constructs a boot stanza that specifies your kernel and RAM disk,
which enables your boot loader to boot your custom OS.
This script is required for an unattended installation and for an interactive
installation that uses virtual media to boot, because the target system's static IP
address needs to be specified in the kernel parameters.
boot_stanza
This script accepts a password from StdIn and outputs the encrypted password
through StdOut, allowing you to encrypt the root password of the target server
for an unattended installation.
encrypt_passwd
This script is used for an installation using virtual media that requires additional
files, in addition to the kernel and RAM disk, to boot.An ESXi OS is an eample
of an operating system that requires additional files to boot.
extra_files
This script is used expressly for an installation using virtual media where the
OS requires an alternate directory structure.
create_iso
Insight Control for Linux provides example auto_config, boot_stanza, and
encrypt_passwd scripts for the CentOS 5 and Debian 5 operating systems; they are located
in the /opt/repository/instconfig/custom/examples/ directory in the
subdirectories named for the OS. HP recommends that you use these examples as templates
for your own scripts.
TIP: When you create a script, make sure that it is executable by the root user.
4. Copy the scripts to the /opt/repository/custom/MyOS directory.
5. For unattended installations, register the installation configuration script with the Insight
Control for Linux Repository:
For information on registering an installation configuration file, see Registering operating
systems (page 51)
