Thanks very much. (btw I didn't mean the question as a criticism.) Part of my confusion was that I misread Buster as Bullseye as I didn't realize Buster was still in use.

This is the specific version of the Debian Bookworm base image that
your instance was created with, it means that on 2024-04-10 a new
image was built to replace that one. That is unrelated to the process
for dropping support for an entire OS release.
I assume we are not encouraged to upgrade the image. Does puppet take care of that?
