uBlue does not repair anything, they dont automatically detect a broken driver on your system and block an update.
This would be possible, but slow down boot (running some GPU benchmark on every boot via a systemd service, if it fails run the commands that I mentioned).
rpm-ostree is awesome, and has the potential to do that.
you don't get the broken update ever on your device in the first place.
In theory yes, but this would mean uBlue is some kind of stable distro. I dont know, at least their base images just get updates.
Their big advantage is that they dont have the legal restrictions, so they can ship 1:1 the system you run. I dont know if they do, but having some automated benchmark tests on real hardware with these devices would be useful.
But that costs a lot of money. uBlues trick is that they can run their whole huge project for free on Github.
But for sure, the dependency issues will not occur. But this does not guarantees that there are no issues on bare metal.
Or a stable branch, Bazzite was longer on F39 for example. I use the :latest
branch which automatically gets upgraded to the latest version, which they determine. So having an :testing
branch that is up to date, and slowing down the releases of the latest branch, could help.
