Fedora uses btrfs by default. I don't think that snapshots are enabled by default, but quick googling reveals some instructions which should enable snapshots for updates. I guess that might help to achieve similar behaviour.

Or, if you want to use Fedora, try Fedora Silverblue [1]. It uses an immutable root filesystem and offers atomic updates and rollbacks through OSTree.

I don't think btrfs is a shining example of Linux stability/reliability. NixOS gives me rollbacks using XFS for root.
