Before Fedora Asahi, I was using OpenSuse Tumbleweed. It sets up automatic pre/post snapshots on software updates and it is possible to boot into such a snapshot. Is it possible to have bootable snapshots on Asahi?
These snapshots saved me from updates that caused software I use to stop working. I remember a graphics driver update that caused my compositor (sway) to not start. I have enabled dnf snapper plugin and that perhaps takes me most of the way there.
I think since fedora keeps at least three kernels, I should be able to boot into one that works and then rollback to a previous snapshot. But this is not as seamless as bootable snapshots.
