I like them a lot, switched to Kinoite⏩uBlue: (Kinoite-main, -nokmods (until that got silently dropped), -main again; 37-39)⏩Secureblue kinoite-laptop-userns
The biggest Problem is that Fedoras Images are not usable.
Filemanager movie thumbnails dont work
Flatpak browsers are not feature-complete and probably not secure (because they can’t create usernamespace-isolated processes for tabs)
they have no NVIDIA support
powerusers will miss ffmpeg
The idea of immutable images is, to have a base that most people dont need to change. You can, but the moment you add NVIDIA proprietary drivers or full ffmpeg, you are in unprotected territory again.
So I like the Distros for their reproducible bugs and future possibility to be a very secure base (you could just verify the hash of the root system to check for viruses). But they cannot be produced in the US.
Fedora is nice but just like with rpmfusion, ublue is the key part that makes it work. And on immutable images this cannot just be added in a welcome dialog, as you need massive overrides by default.
