The goal of btrfs is to not become inconsistent in the first place, and the reason why it
can happen is pretty much always some kind of hardware problem. If there's extent tree
corruption on any file system, beginners will have difficulty. The btrfs repair experience
could be more involved than ext4, because with ext4 either the fsck works or it
doesn't. Whereas with btrfs there are more opportunities for both failure and recovery
due to the nature of copy-on-write and the fact everything including data is checksummed.
This won't be a common occurrence, but it's valid to wonder what this experience
will look like, and ensure the Fedora user to user community is ready.
