Jumpstart Rules File

The rules file is a text file used to create the rules.ok file. The rules file is a look-up table consisting of one or more rules that define matches between system attributes and profiles. For example, the rule 

	karch sun4c - basic_prof 

matches a system with a sun4c platform name to the basic_prof  profile, which the Solaris installation program would use to install the system.

During a custom Jumpstart installation, the Solaris installation program attempts to match the rules in the rules.ok file in order: first rule through the last rule. A rule match occurs when the system being installed matches any of the values in the rule (as defined in Appendix A). As soon as a system matches a rule, the Solaris installation program stops reading the rules.ok file and begins to install the system as defined by the matched rule's profile.  This allows a fine grain control over different configuration clusters:

#### [!]keyword value [&& [!]keyword value] ... begin      profile      finish

#

#

             any -   -   any_machine  -

              ^  ^   ^       ^        ^

              |  |   |       |        |

              |  |   |       |        -------------- Finish script

              |  |   |       --------------- Profile

              |  |   -------------- Begin script

              |  ----------- Rule Value (specific system attribute)

              ----- Rule keyword (general system attributes)

Example:

 Validating the rules file

Before the profile server is able to function the jumpstart share must have a rules.ok file.  The check script validates the rules file and creates the rules.ok file.
