I find this scary in the sense that users need to know about these modules to get the benefit of recovery, and even then, they also need to know they are affected by this problem when they install GRUB (since otherwise they won't be able to bootstrap). Is it possible to detect whether recover code will be needed when grub-install is run, and then either add the extra modules or abort with an error? -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
