allows automatic fixes to be applied to a broken driver without requiring any manual intervention from its user.
If you get an update, and after that update your system doesnt graphically boot anymore or something, you can use sudo ostree admin pin 1 and rpm-ostree rollback to switch back to the working version and make sure it never disappears.
Then you can wait for a next update (still no good update info mechanism afaik) to fix it, try it, unpin the saved version and go on.
But there is no automatic repair voodoo anywhere, on any distro. That driver is proprietary, only NVIDIA can fix it. rpmfusion packages it to work on Fedora, Fedora Atomic helps making this very unstable mechanism more failsafe.
But you are still relying on 3 entities (NVIDIA, rpmfusion, Fedora, (uBlue)), with NVIDIA not caring about Linux that much, instead of 1 (Fedora) like with AMD, where drivers are FOSS and can be adapted for Fedora specifically.
AMD does not opensource a lot, and ROCM or the entire amdgpu-pro driver is a similar situation. But at least the basics work.
