The classes body applies to all promise types, including class promises, right?

Persisting a class seems to be tied to a classes body. Suppose I want to
persist a class defined in a classes section instead. Is this possible
menting.
My thoughts exactly. Why outsource to external scripts when Cfengine can
do the job. While for now this is merely of theoretical interest to me,
I can imagine real-life scenarios where class persistence may prove to
be a useful feature.

You can set a different ifelapsed for any promise you like.
body action if_elapsed(x)
{
ifelapsed => "$(x)";

Yes. The logic that defines the class is run every hour, but the
resulting class lives on for 120 minutes or until it is reset by another
run of the logic
roach, I would have to maintain the persistance state in
the module script (state file or whatever), which is not ideal. I'm
trying to avoid this by making Cfengine remember the class.

Thanks for the suggestion, Michael. Modules may very well be the
answer. But if I understand modules correctly, they are just little
scripts/programs that are executed by Cfengine and return classes. Not
very unlike using stringcmp() and execresult() like in m

I think you want to change the class strcmp to a command action instead. Then
define the class as repaired or not.

I'm pretty sure modules can do what you want. They are programs that are
executed by cfengine, and return in serialized form a stream of classes to
be defined (or undefined). You can make that program as smart or dumb as you
want, and simulate things like persistent classes.

Hi,
I've been playing with class persistence recently. The idea is to run
potentially heavy class-generating commands not too frequently, but
being able to use those classes every time Cfengine runs.
What I have now is this:
