I just noticed it completely skipped to restore my root subvolume.
Maybe because it was originally restored from a snapshot (during a
previous btrfs corruption issue) and so somehow it thinks it's still a
snapshot?
How can I restore it? I cannot afford to restore all the snapshots, I
don't have enough free space to do so.
