Advanced Installation - Solaris 9 System Administrator - page 385

reside on a floppy disk, referred to as a profile diskette , or on a network serv-
er, referred to as a profile server . The profile server provides access to the cus-
tom JumpStart configuration files over the network and eliminates the need
to create and distribute multiple profile disks during installation of a large
number of systems. The two basic types of files in the JumpStart directory
are the rules file and one or more profile files.

The Part II Exam (310-015) continues to refer to the “profile” file as the “class” file
even though it was renamed way back in the Solaris 2.6 system documentation. Keep
this in mind when you see JumpStart questions that refer to the “class” file.

The Rules File
The rules file is a text file that contains an entry or rule for each system or
group of systems that are to be automatically installed. Each rule identifies
the system (or group of systems) based on one or more attributes and iden-
tifies a unique profile file that provides the configuration details for that sys-
tem or group of systems.

Each rule consists of one or more keywords and values followed by the name
of a begin script, the profile file, and then the finish script (all separated by
tabs or spaces). Keywords (and associated values) include the following:

➤ any

➤ arch (followed by a processor-type value)

➤ disksize (followed by a disk name value)

➤ hostaddress (followed by an IP address value)

➤ hostname (followed by a hostname value)

➤ memsize (followed by a physical memory value)

➤ model (followed by a platform name value)

One or more of these keywords and associated values are specified per rule
to uniquely identify a system or group of systems.

Following the keywords and values is the name of a begin script. This is a
Bourne shell script that executes before installation begins. If a begin script is
not required, a hyphen (-) should be specified instead. Following the begin
script is the name of a profile file in the JumpStart configuration directory
that provides the configuration details for that system or group of systems.
Following the profile file is the name of the finish script. The finish script is
a Bourne shell script that is executed after installation is complete. If a finish
script is not required, a hyphen (-) should be specified instead.
