(And you can then subsequently access the original root of the filesystem using mount -o subvolid=0). > II. it is so easy to create raid arrays of btrfs partitions but they > cannot be read by f13 or f14 There's no particular reason that this should be the case. How do you come to this conclusion? What did you try, what did you expect to happen, and what actually happened? > III. it is not possible to copy btrfs partitions with snapshots > except possibly by the use of dd. Again, I can't see a reason that this shouldn't work. What are you trying to do, exactly, and how is it failing?
