As far as I understand, so far Ansible only supported CoreOS Container Linux, which will be soon EOL. Recently there was an attempt to support Fedora CoreOS or RedHat CoreOS, which was not merged. I am not sure if there is any recent progress about that.
So would it be reasonable to simply add new code for Flatcar, just like CoreOS Container Linux?
