Comment 4 for bug 149832

I think we should backport this for Ubuntu 8.04.2. I'm discovering quite a few installation failure reports due to this (I suspect many of those that say "the file /boot/grub/stage1 not read correctly" are due to this, since grub will fail to mount a filesystem using its internal filesystem libraries if the partition has the wrong type), and I think backporting this one would be an easy big win.
