Title:
  Provide way to pass rootflags=degraded (for btrfs)

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  Right now, /etc/grub.d/10_linux insists on

              GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol}
  ${GRUB_CMDLINE_LINUX}"

  and the only way for me to tell a remote box that booting with a
  degraded RAID1 for a btrfs root filesystem is via

  $ grep degraded /etc/default/grub 
  GRUB_CMDLINE_LINUX="rootflags=subvol=@,degraded"

  but this is brittle because it doesn't do the ${rootsubvol} logic from
  /etc/grub.d. Please provide a better way.
