A few days ago I tried to copy my backups to another machine by using
my external hard drive. `btrfs send my-backup | btrfs receive
/path/to/backup/dir` didn't go right since destination snapshot's
"Received UUID" does not match with source's "UUID". Here are relevant
stackoverflow question:

Is it a bug?

Well, "btrfs send" will use received UUID instead of subvolume UUID if
one exists. I presume intention is to be able to replicate received
subvolume. So A -> B -> C has the same effect as A -> C, making C yet
another copy of A.
