Comment 45 for bug 1530953

The right fix is here:

If you bring 0.6.5.6 and patch Ubuntu's GRUB to set that environment variable, then the udev rules can go away entirely.

Otherwise, as to the debdiff in #38, it is fine, but the "raid" condition is unnecessary as per my and dasjoe's previous comments.
