Since I had to explain this very same thing to a new btrfs-using friend
just yesterday I wondered if it might not make sense for mkfs to issue
a general balance after creating the fs? It should be simple enough
(just issue the balance ioctl?) and not have any negative side effects.

Just doing such a post-mkfs cleanup automatically would certainly
reduce the number of times we have to explain the this. :)

Any reasons why we couldn't/shouldn't do this?
