How quickly and safely are bugs fixed in Bluefin?

It looks like Debian equivalents might be VanillaOS, EndlessOS, and (though not as similar) StarlingX, since all are OSTree-based for atomic updates.

I’m curious what others’ experience is with developing on these- do drivers work out-of-the-box and is it easy to configure, similar to macOS stability with something like brew to get latest packages and apps?

Eventually I’ll probably have to go back to free OSes because things don’t seem to be getting better.

As soon as Fedora/Centos updates their images (pretty much immediately usually as it's upstream of EL), and the CI runs to re-layer the Bluefin changes. They also have Dependabot set up. https://github.com/ublue-os/bluefin/actions

It's just OCI images, like any web-scale project.
