If the refreshonly attribute is set to true in an exec resource, what does it imply about the execution behavior?

When the refreshonly attribute is set to true in an exec resource, it indicates that the execution of the resource will only occur when the resource is explicitly notified by an event from another resource. This is particularly useful in scenarios where you want to minimize unnecessary executions, only allowing specific actions to trigger the exec resource based on changes from other resources. For instance, if a service is updated and configured to notify the exec resource, that resource will only run if the service change triggers it, rather than during every Puppet agent run. This results in a more efficient and event-driven application of configurations, leading to reduced resource consumption and improved performance during Puppet runs.
