Code review comment for ~juliank/grub/+git/ubuntu:resilient-boot

I'm also confused about the previous check to EFI/ubuntu exists on the ESP, because I want people to use the grub-multi-install wrapper to do the initial installation too, until we have this sorted out properly in grub-install (which let's face it, is a lot of work).

Because I can add a hack to grub-install now reasonably quickly, but I don't see that getting a clean solution, because that's touching a lot of places, and that's (a) a lot of work and (b) a huge effort to maintain downstream.
