Ok thanks.

Small question: will you also immediately release a new package for fedora 38, with the current latest docker, or you will wait the next point release of docker ? I am asking because on our side some builds are broken since about a week because of this issue ;)

Also, for fedora 39 should the packages be created already now or we still wait a bit ? See docker/containerd-packaging#315

It may be a bit early to already start publishing packages, but we can look at adding them to CI already (although I think the rawhide image is currently still the same as 39)
