bootc is a great evolution for rpmostree IMO. Fedora Atomic had decent build tooling, but all of that was thrown away for Fedora CoreOS due to the ignition use. I was never a can of Fedora CoreOS but I really liked Atomic. This seems to be a sensible pivot back the other direction. We don't need the CoreOS parts that never really delivered any value. And now building an system image is a simple as writing the container file. This way of doing things probably offers little to the average Linux user. However, it's a great model for distributing 'appliance' images, or having transactional updates on your servers. In the cloud, transactional updates aren't that big of a deal, you can do a rolling replace of your instances. On bare metal machines, doing in-place transactional updates is a big win. Rancher also has an interesting project called Elemental. It seems to be a little more portable for other distros, but I haven't played around with it.
