Use a text editor to create a Bourne shell script text file. Name the file custom_probes.
In the custom_probes text file, define your probe and comparison functions.
You can define probe and comparison functions that require arguments in the custom_probes file. When you use the corresponding custom probe keyword in the rules file, the arguments after the keyword are interpreted in sequence (as $1, $2, and so on).
When you use the corresponding custom rule keyword in the rules file, the arguments are interpreted in sequence after the keyword and before the next && or begin script, whichever comes first.
Save the custom_probes file in the JumpStart directory next to the rules file.
Ensure that root owns the rules file and that the permissions are set to 644.
