Meaning if the cloud-init data is not moved then it always looks like a new instance is being booted.That sounds like a flaw in transactional-update. As a user, I would be very surprised to see persistent data being thrown away. I would expect /var/cache to be emptied, but not /var/lib. I think you need to go back and fix that instead.
Indeed. /var/lib is where we store things like package manager metadata, logrotate state, and much more. While it is true that /var is meant to contain things frequently updated (as opposed to the relatively static /etc), /var itself is not ephemeral and must survive reboots for stateful machines/VMs. Specific directories within /var might be ephemeral or mounted as tmpfs, such as /var/run or perhaps even /var/cache.
/var/lib, however, should be preserved. It sounds like /var/lib and /var/cache are being used backwards in the situation described.
