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. The sequence starts after the keyword and ends 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.
