Hello Dave, Our best practice, in your case, is to modify the script that launches a new instance to always make sure you boot from the latest image in the suite you are running. On an officially maintained cloud, our images are updated as soon as a security update that mandates it is published, or at least every two months. This means that by launching the latest image, you are quite unlikely to have a kernel update to be done. This also limits the number of updates that you will have to pull, over time, for a given suite. To do so on EC2, I would recommend using the query interface on cloud-images.ubuntu.com [1]. Look at the file and URL, I think it is self explanatory, but more explanations are available at [2].
