Very small btrfs filesystem require special handling, mixed block
groups in particular, which I believe also requires an updated mkfs
from the integration repo.
Thanks for your response, however, even if I enlarged the image size to 2G,
still got no luck.
Per Zefan's comments, run 'btrfs device scan' fixed this issue.
you should be able to achieve this via `device=` mount option(s?) as well:

... for completeness :-) ... and posterity or whatever.
Nice, thanks for your sharing. 8-)
