[Bug 736743] Re: environment block not implemented on btrfs

[Sami Näätänen]

OK so I actually found out how to do the above thing.

So apply the provided patch for /etc/grub.d/00_header.
Original used for patching is from Ubuntu 17.10 (GRUB 2.02~beta3-4ubuntu7.3).
Move or create your grub env block file to efi partition:
ubuntu original location: /boot/grub/grubenv
patch location: /boot/efi/EFI/ubuntu/grubenv
Run update-grub2 to create the new grub config.

I do not know what EFI specs or something like that
says abount using EFI partition for the GRUB env block,
but it DOES work for me.

Title:
  environment block not implemented on btrfs

Status in grub:
  New
Status in grub2 package in Ubuntu:
  Triaged

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.
