Do you need a bona fide error to be generated, or would it be sufficient to deliver a catalog containing only a notification message? For example, given the following class available on your master, class site::no_window { notify { 'no valid change window open': } } , if the ENC determines that it is outside any change window for the target node then its output can be simply classes: - site::no_window . Supposing that you have neither any global declarations nor a node block for the target node, that will result in no changes to the target, except possibly Puppet plugin synchronization. The notify message will appear in Puppet's output. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
