That seems like the real issue here - what am I missing? Regardless, if we can't count on fwsetup being updated, then I think we need to go back to the original version of my patch which doesn't have --is-supported. > Simply don't break user-space when older grub got installed to MBR. > Somehow this idea needs some more thinking and a solution for that > case too. Sure, what do you suggest? Be well, --Robbie
