Is there a constructive summary anywhere of what LVM needs
to do / change? This problem affects libguestfs too.

I Want To Believe in btrfs, but unfortunately it's still excessively
buggy. It's actually got worse in Rawhide recently -- it reliably
fails in mkfs.btrfs :-( I stopped bothering filing bugs about this
because they just get ignored because Rawhide isn't "new enough" (they
want us to retest everything on some non-upstream btrfs-next kernel).
My colleague ran btrfs on his laptop and had daily crashes. Last week
he went back to ext4.
