Customizing the Solaris Installation on the Master System

After you install the Solaris operating environment on the master system by using any of the Solaris installation methods, you can add or delete software and modify system configuration information as necessary.

• Delete software. You can remove software that you determine is not necessary to install on the clone systems. To see a list of software that is installed on the master system, use the Product Registry. For detailed instructions, refer to System Administration Guide: Basic Administration.

• Add software. You can install software that is included in the Solaris release. You can also add software that is not delivered as part of the Solaris operating environment. All of the software that you install on the master system is included in the Solaris Flash archive and is installed on the clone systems.

• Modify configuration files. You can alter configuration files on the master system. For example, you can modify the /etc/inet/inetd.conf file to restrict the daemons that the system runs. All of the modifications that you make are saved as part of the Solaris Flash archive and are installed on the clone systems.

Further customization can be done when creating the archive. For example, you can exclude large data files that you might not want in the archive. For an overview, see “Customizing the Solaris Flash Archive Files and Directories”.

After you install the Solaris Flash archive on a clone system, some host-specific files are deleted and are re–created for the clone machine. The installation program uses the sys-unconfig(1M) command and the sysidtool(1M) programs to delete and re–create the host-specific network configuration files. The files that are re–created include such files as /etc/hosts, /etc/defaultrouter, and /etc/defaultdomain.
