Update the rules File

Now you must add rules to the rules file. The Solaris installation program uses the rules to select the correct installation (profile) for each system during a custom JumpStart installation.

At this site, each department is on its own subnet and network address. The engineering department is on subnet 255.222.43.0, and marketing is on 255.222.44.0. You can use this information to control how the engineering and marketing systems are installed. In the /jumpstart directory, you edit the rules file, delete all of the example rules, and enter:

network 255.222.43.0 - eng_prof -
network 255.222.44.0 - marketing_prof -

Basically, these rules state that systems on the 255.222.43.0 network will be installed using the eng_prof profile, and the systems on the 255.222.44.0 network will be installed using the marketing_prof profile.

These are sample rules in which you can use a network address to identify which systems will be installed with the eng_prof and marketing_prof, respectively. You could also have chosen to use host names, memory size, or model type as the rule keyword. See Table 8-2 for a complete list of keywords you can use in a rules file.
