There's also a runtime flag in `/run/ostree-booted` that will be set to `1` if the system is an "atomic" or rpm-ostree based install. That's how the Ansible content I've seen and used test's for `is_atomic`. It's not something built in, so it's a local fact set during run of the playbook.
I'm not familiar with docker-machine, so can you elaborate on how `/etc/os-release` would help here? Can docker-machine extract that file without having to SSH to the host? We've talked previously about asking for an "Atomic" flag in os-release or fedora-release, but there haven't been a lot of concrete use cases to base it on.
