Comment 53 for bug 736743

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.
