Well, it's not a patch. It's a workaround for those who have btrfs
installed. The rest non-btrfs based systems still want those 4 lines.
Please note that cjwatson is maintainer of grub2 and he proposed this as
a dirty workaround not a solution that we can apply and upload into the

  environment block not implemented on btrfs

Bug description:
  Binary package hint: grub2

  I just installed natty alpha 3 on a samsung NC10 netbook. When booting, immediately after the grub screen I see the error message:
  'sparse file not allowed. 
  press any key to continue'
  after pressing any key the boot continues as normal.

  This is with btrfs on / and a separate ext4 partition for /home. I had
  created the btrfs partition manually (i.e. in a shell outside
  ubiquity) simply running mkfs.btrfs /dev/sda1 and it was not
  reformatted in ubiquity.
