end

#enableable?(action) ⇒ Boolean

This is a hook for subclasses to be able to tell the super class that a service is or is not enable-able. For example, on systemd, static and indirect units are not enable-able.

In addition, this method offloads the messaging to the user. If the method returns ‘false`, it should say why `action` couldn’t be taken

Returns:

  • (Boolean)

end

#load_new_resource_stateObject

the new_resource#enabled and #running variables are not user input, but when we do (e.g.) action_enable we want to set new_resource.enabled so that the comparison between desired and current state produces the correct change in reporting. XXX?: the #nil? check below will likely fail if this is a cloned resource or if we just run multiple actions.
