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

[Dmitrijs Ledkovs]

Reading the documentation [1] it leads to believe that load_env is
excluded from certain type of systems. Yet reading the code I did not
find those guards (maybe they are not explicit). In any case, until
blocklists are implemented for btrfs, load_env should not stall the
boot. Showing warnings is fine, but should not stall the boot. load_env
can fail for many reasons outside of grub's control, but I don't see why
this is so important to require user input.

I will try this again with recent 2.00 packages.

Title:
  environment block not implemented on btrfs

Status in GRand Unified Bootloader:
  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.
