Title:
  [Natty] [BTRFS] grub 2 won't install if /boot is BTRFS

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub2

  After converting a whole system from ext3 to BTRFS, trying to
  reinstall grub2 with a BTRFS /boot results in :

  root at tethys:/# grub-install /dev/sda
  /usr/sbin/grub-setup: warn: Your core.img is unusually large.  It won't fit in the embedding area..
  /usr/sbin/grub-setup: warn: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
  /usr/sbin/grub-setup: error: will not proceed with blocklists.

  Only solution found so far : Convert /boot back to ext2, and proceed
  with the rest of the system on BTRFS, except for /boot.
