My patch presents a reliability paradigm: accept all inputs, produce outputs that are always aligned to 8-byte. It can make sense even though I agree that requiring 8-byte alignment for UUID is weird. Yet it's difficult to know if some obscure firmware does rely on it in some one in a thousand edge case > > [1]: > https://github.com/torvalds/linux/blob/master/include/linux/efi.h#L60-L78 > > [2]: > > https://github.com/torvalds/linux/commit/494c704f9af0a0cddf593b381ea44320888733e6 > > I know I mentioned [1] earlier, but it sounds like it might have slipped > through and it might be a good idea to have both GRUB and Linux in sync > in this regard. > > Cheers, > Frank >
