Base images

Many users will be more interested in base (container) images.

Fedora/CentOS

Currently, the Fedora/CentOS bootc project is the most closely aligned upstream project.

For pre-built base images; any Fedora derivative already using ostree can be seamlessly converted into using bootc; for example, Fedora CoreOS can be used as a base image; you will want to also rpm-ostree install bootc in your image builds currently. There are some overlaps between bootc and ignition and zincati however; see this pull request for more information.

For other derivatives such as the "Atomic desktops", see discussion of relationships which particularly covers interactions with rpm-ostree.

Other

However, bootc itself is not tied to Fedora derivatives; this issue tracks the main blocker for other distributions.
