> Just an Ubuntu/Debian thing, but snapshots are not integrated into the update process unless you install `apt-btrfs-snapshot` (and know that package exists) Thanks - I did not know about that. I agree with the stance of not mounting a degraded RAID automatically as then the danger is that someone might not notice it and be subjected to total data loss later on. The best option would be to allow over-riding that choice if the RAID is otherwise monitored.
