Btrfs snapshots not always work tho), i tell this story for *th time on lemmy but my fedora 38 btrfs broke completely from update to 39 and when i tried revert to 38 with help of btrfs snapshots, what came out is weird mix of 38 and 39 and when i reverted again, my whole ssd on which fedora btrfs was installed, this ssd locked completely, on hardware level, even though it was brand new, 2 weeks of usage by me, i fortunately repaired ssd myself and flashed lmde6 on it, but avoided btrfs and fedora after that
Was using btrfs then in manjaro, broke my laptop because btrfs seems to be shit at handling loss of power cases. Switched to good ol ext4 and nixos, never looked back since.
