Comment 4 for bug 78552

Ben Collins:
kernel-image.conf is not something the kernel manages. It's done by the installer.

Therefore ubiquity is going to deal with that and a brand new installation is going to have kernel-image.conf set correctly.

People upgrading from edgy to feisty will either have to edit the file manually or fortunately, the update-manager will deal with that when upgrading from edgy to feisty.

Maybe update-manager should be modified in such a way that when a distribution upgrade is performed it will check for any instance of /sbin/update-grub and replace them with /usr/sbin/update-grub
