Great. I pulled it a while back, and I am happy to know that it work.
But I tested on Raspberry Pi today, and the image do not boot because
the root file system isn't found. I suspect it is because the kernel
used isn't a debian kernel with the btrfs kernel module loaded, but
did not spend much time investigating. Switching to ext4 got the
system booting again. Anyone got a clue how to get this working with

No idea. Do not quite understand what you mean by "the top of the
btrfs filesystem". @ is mounted as /, and what I believed to be the
top is mounted as /btrfs/, to ensure @ kan be snapshotted below
/btrfs/ and used during boot if one want to jump back to a earlier
version of the root file system.
