How can one copy the contents of a btrfs filesystem? This would include snapshots, subvolumes, etc.

dd is not enough, since it duplicates the UUID, and there isn't a way to easily change it, apparently.

There is a similar question on unix.stackexchange.com that points to partclone.btrfs, but I do not know any specifics about this.

There is also a discussion on the kernel mailing list, not really looking promising...

With btrfs-send, which last I saw, was still experimental patches floating around on the btrfs mailing list.
