Comment 10 for bug 1918427

I tested this locally by creating a MAAS preseed that adds my PPA. And it works.... sort of. The kernel no longer causes flash-kernel to be installed, but unfortunately flash-kernel is *pre-baked* in the arm* cloud images, so we'd have to remove it from them too.

RE: EFI-STUB - GRUB is the default way to boot Ubuntu on EFI systems. Users can choose to boot using EFI-STUB, but they can also remove any Recommended packages. Adding grub-efi-arm64 to Recommends will also get arm64 on-par with amd64, which also recommends GRUB.
