They've finally caught up with buildroot and embedded Linux best practices. Partition swapping has only been around for 30 years or so...
Amazon Web Services has begun previewing Bottlerocket, a new open-source Linux distribution designed for running containers. There are two main ideas behind Bottlerocket. The first is to make it easier to automate OS updates by applying them in a single step, rather than package by package. According to AWS, this will also …

If Amazon is having trouble running the build root script and creating Linux partitions, we all have bigger problems.

Then he had the sheer audacity that he was looking for someone to do more than toggle a few GPIOs. Needless to say, I didn't bother speaking to him again.
But there are alternatives, there are many ways to skin a cat, but you don't even need dynamic libraries in a non multiuser system.
isn't the issue of OS updates more to do with the system packages vs app packages breaking compatibility and not really a boot issue?
I wouldn't say cloning and rolling back images are as helpful when you need to isolate the offending package or library update that broke it ...
