I can look into this, but I'm afraid we'd need two helpers, because of IDE complications. When it comes to block device models, IDE is *always* the troublemaker. And a big reason for that is the messy data structures that are impractical to clean up while we still support non-qdevified IDE. Which we do almost three years after IDE qdevification. The laggards are: * mac99, g3beige Alexander Graf <ag...@suse.de> * spitz, borzoi, terrier Andrzej Zaborowski <balr...@gmail.com> * tosa unmaintained * r2d Magnus Damm <magnus.d...@gmail.com> Any plans to drag these boards into the current decade already?
