Per a mutual decision, Universal Blue’s old custom image tooling has now been transferred to the BlueBuild org and development will be continuing under the BlueBuild project with basically the same team of maintainers and developers as before. The issue was discussed extensively in ublue-os/startingpoint#223 and eventually voted for in ublue-os/main#476.
We’ve been working on BlueBuild for a month now to provide you a smooth migration and exciting new features, so don’t worry, this change is positive.
To briefly summarize, this desire to split stemmed from a difference in philosophy and scope between the main Universal Blue maintainers and the developers of ‘startingpoint’. Since most of the Universal Blue project’s build systems use classic cloud methodologies like Containerfiles and GitHub Actions directly to build their images, the abstraction introduced with recipes in ‘startingpoint’ might have seemed unnecessary. Additionally, I felt that as a subproject of Universal Blue, this project couldn’t really achieve its full potential.

Currently, it’s indeed only for Fedora based distros. But there already have been efforts to make it work with Vanilla OS. And I assume that similar endeavors might occur if other image-based distros are provided. I wonder if such efforts are in the works for blendOS (an atomic distro based on Arch).
I don’t know what your exact use case or intended usage of it will be. But, perhaps, penguins-eggs is what you’re looking for.
