Based on this comment it sounds like maybe you hit a bug in an Ubuntu image and didn't know where to file it? If so, upstream cloud-init is likely not the right place, but if you share some details about your issue, we can try point you to the right project.

Are you experiencing something similar to that bug you linked?
