To set up your site to install Solaris software on systems over the network with no user intervention, you must:
Preconfigure network information for the systems, such as the date, time, geographic region, site subnet mask, and language. This eliminates many prompts that are otherwise necessary to identify the systems during an installation. (See Chapter 6, Preconfiguring System Configuration Information.)
Set up the custom JumpStart files for the systems. (See Chapter 8, Preparing Custom JumpStart Installations.)
Set up the systems to install over the network. (See Chapter 7, Preparing to Install Solaris Software Over the Network.)
