   You can use btrfs subvolume set-default to set the default
subvolume that is mounted if no "subvol=" or "subvolid=" parameter is
given to mount. (And you can then subsequently access the original
root of the filesystem using mount -o subvolid=0).

   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?

   Again, I can't see a reason that this shouldn't work. What are you
trying to do, exactly, and how is it failing?
