Comment 3 for bug 872244

FYI: The Ubuntu community proposes the use of a grub2 error script to deactivate the recordfail logic, preventing from problems in RAID/LVM/btrfs environments. I find that a somewhat "cleaner" approach than to edit 00_header directly, whose changes might be overwritten by upgrades. The error script replaces the according functions by hollow routines.

Here's the link to the workaround/solution from the german ubuntuusers wiki:
http://wiki.ubuntuusers.de/GRUB_2/Skripte#Fehlerskript-LVM-RAID

Put this as an executable script under /etc/grub.d/02_kill-save_env, do an update-grub, and you should be set up. At least in my case it seems to have worked (can't say exactly, because I used the fix on a headless system and cannot debug completely _why_ it works now :-)

Cheerz, Martin

PS: I strictly vote for a server version/mode of grub2 in Ubuntu. We (I) don't need recordfail, recovery, os-prober or pretty gui there, and it's cumbersome to strip down the grub2 functionality monster to a sweet server-compliant puppy. I really like the monster on desktops, but IMO it bears too much potential to break servers "by default".
