I don't understand. Which kind of maintenance do you mean? GRUB isn't designed to modify partition maps, only read them. Perhaps what you want is more related to Parted? > > Isn't this what GRUB does already? I thought it would be... > > > It does. But I don't know if there are other cases similar to this one. There's also grub-setup. On an hybrid map the only option is to follow the GPT install path and search for a BIOS boot partition (or otherwise use blocklists). Does it DTRT already? I don't know of any other similar situation. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
