I know this difference. But, in my opinion, the resize should only be a
stupid workaround for a single box.

Ive parted my system with the debian installer for i think 4 months.
Grub2 worked fine until the upgrade on Dezember 1.

- - If this is the only good solution, the parted app may start the first
partition at the second cylinder by default.
- - Or, the better idea, grub should reduce the size of its driver modules.
- - Or third idea, posted by thomas, is to remove the raid module if it is
possible.
