Comment 5 for bug 700910

It appears that this only resolved problems when grub was being installed to another partition. There is still some breakage when trying to install it to the same one as booted. Here's /proc/self/mountinfo from a failing system with an ISO built on 1/18 (Grub2 1.99~20110112-1ubuntu1).
