I think the view is that this is the job of udev, not btrfs. Presumably 
you can use udev rules to give block devices arbitrary names.
Maybe it might be useful if there was an option to btrfs-progs so that 
it printed the symlink names in /dev/disk/by-partlabel if present.

Yeah, I've had the same idea - this is something that's definitely 
possible, it just needs someone to implement it.

If we're writing a wishlist, I'll add:

BAD SECTOR TREE

i.e. a list of sectors known to be bad that the allocator should avoid, 
in the same way that it avoids the superblocks. NTFS has something 
similar, and I think ext2 does too.
