I'll let Steve comment on this, but having had to deal with far-reaching consequences of that very change, that seemed trivial enough, Im very much not convinced I'd like to see more things getting tweaked there. I acknowledge that this means a maintenance burden for downstream distributions that would like to use an unsigned GRUB. But then, that's their choice… Cheers, -- Cyril Brulebois (kibi@debian.org) <https://debamax.com/> D-I release manager -- Release team member -- Freelance Consultant
