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:
|
# The following rule matches one system: hostname host1 - host1_class set_root_pw # The following rule matches all x86: arch i386 x86-begin x86-class - # The following rule matches any system: any - - any_machine - karch i86pc - basic_prof - |
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.
|
Usage: check [-r <rules filename>] [-p <Solaris 2.x CD image path>] |
