Comment 9 for bug 1918427

Hi Dann

I'm not sure how to test custom kernel with Curtin during installation.
I will try to install it into non-flash-kernel system and see APT will install it or not.

As your advice, I have a question about this.
If this question isn't critical, I think this should work.
Do we need to consider about someone who will want to use EFI-STUB to boot directly?
If so, maybe we shouldn't add grub-efi-arm64 to recommends?
Because it will install unnecessary package for them.

grub-efi-* will be installed in `install_missing_packages` stage before `install_kernel`.
So flash-kernel will not be installed if grub-efi-* is installed and in recommends of kernel.
