Flatcar Container Linux is a drop-in replacement for CoreOS Container Linux which in my mind (I conceived the fork) makes it more than "an (almost) equivalent alternative". You can literally update straight into Flatcar from CoreOS using the standard update process. See https://docs.flatcar-linux.org/os/update-from-container-linu...

So, Flatcar is to CoreOS as Centos is to RHEL (if you ignore that CoreOS is going away). The differences make it not entirely analogous, but it's probably an easy way express it in very few words.

Currently for the stable and beta channels that is true for now. Of course that changes in May when we fully take over maintenance. But for the alpha channel, and experimental edge channel, we have already diverged with updated packages.

But, yes, in the beginning we simply removed the CoreOS trademark similar to how CentOS removes the RHEL trademark. But very different from CentOS, we knew from the start that the upstream would eventually go away and all maintenance would be carried by Kinvolk and other contributors.
