Besides the guts of how the OS platform itself is built and runs, the major feature difference is that it doesn't have all the cluster co-ordination bits like etcd, fleet, and so on.

You can easily run etcd in containers. In fact, at work our etcd deployment are all the official coreos/etcd docker images. Fleet is majorly tied to systemd so that's a different matter.

There's CoreOS the OS and there's CoreOS the project. The OS is just a self-updating barebones Linux distro built for hosting Docker containers.

Which is also very different to RancherOS, but I excluded how the OS is built and run from my previous answer.
