For anyone using Docker and thinking of trying out Fedora, here is a warning:
Fedora uses cgroupsv2 to push things forward, but no Docker release supports it yet, it's in master[0], but there are no release in sight as there is no ETA.

There is only one 'gotcha' that I've hit, when building images specifically for AWS's ECR or Docker Hub, you need to add the flag `--format=docker` to your build step. Quay and a few others don't have this issue.
Curious you mention needing `--format=docker`; I’ve pushed images to Docker Hub without doing that without issue.
It's been a hot minute since I hit that issue, but I kind of doubt docker hub fixed it. I suspect fixing issues around OCI format images are fairly low priority for them.
Edit: This still works in 33: https://fedoramagazine.org/docker-and-fedora-32/
The only difference between what they have here and what I do is that I install docker-ce from the 31 repo, as the seem to have some SELinux related change in there that doesn't require me to label volumes like installing moby-engine does.
One small tweak to the article, for Step 2 I didn't need to use Moby in place of docker as by the time I set things up the `docker-ce` package was available for Fedora 32.
I no longer trust the Fedora maintainers.
That said the RHEL people will be paying attention. If btrfs proves successful, I could totally see it going into RHEL 9.
Disclaimer: I work for Red Hat but not on Fedora. I'm just a happy Fedora community member for a little over 10 years now
I'm sorry to lose your trust. I think that comes from a misunderstanding about expectations. We want to provide a functional, usable system -- but we also are going to change things in new releases, and while we do weigh user impact, we're tilted towards bringing upstream innovation to users. That means we're likely to bring you things like cgroupsv2 sooner rather than later.
If you have these expectations, I hope we're holding to them pretty well. See our mission and foundations page at https://docs.fedoraproject.org/en-US/project/, and hopefully that will make things more clear.
