Command return value in cfengine 3.2

[Bob]

First, I am working to upgrade to cfengine 3.6.

However, I am using cfengine 3.2 now. I need to run a command to check if the kernel on disk matches the kernel that is running. The command has 3 return values:

0 means they match
1 means they do no match
anything else means the result could not be determined

Is there a way with cfengine 3.2 I can detect all 3 of these conditions?

You can use the three possible sets of return codes
(kept/failed/repaired):

Does that work in 3.2? If not write a module to output classes based on
your results.

According to the docs these body attributes were introduced in 3.1.3.

In this case, I think the module is a better solution because no real repair can be done.

I appreciate both suggestions.
