It would be nice to be able to have the node names set, but in Jenkins and in AWS. In Jenkins, the Instance name is used, which isn't terribly meaningful, but useful for cross-reference. In AWS, the name in left empty. Ideally, each AMI should have an "Instance Name" setting. In Jenkins, it is used for the node name, perhaps with the instance ID in perens after it so it will be unique. It would be cleaner to have a simple incrementing number in the name instead though, and then move the instance ID to the description field so we don't lose that potentially useful information. In AWS, the instance name should be set to the same value as it is in Jenkins.
