I have been using btrfs as my rootfs on all my machines for a couple
of years and never seen a corruption that required fsck, so I don't
know how well (or not) btrfsck actually works. I would assume it would
not be too bad, as it is shipped by at least Oracle. The problem
though is that it does not implement the correct API for integration
with regular fsck, so it can only be called manually and not
automatically on boot.
