I get truly confused when using GRUB. Maybe it’s just me being unwilling to dive into all the details, but seriously, why are there like 30 packages starting with 'grub' under Debian? All I want is to boot my kernel under EFI, and the package choices are overwhelming.

  grub-common
  grub2
  grub2-common
  grub-efi-amd64
  grub-efi-amd64-bin
  grub-efi-amd64-signed
  grub-efi-amd64-signed-template
  grub-efi-amd64-unsigned
  grub-efi
  grub-pc
  grub-pc-bin

Do I need to mix grub2 and grub packages to get it to work? Currently I do, and a bit afraid to remove one or the other :)

Usually, I end up trying things randomly (leaving some funny mess in /boot/EFI b/c not sure if --efi-directory should contain /boot/EFI prefix, or just /boot or nothing), then running some semi-random grub-install command, and eventually, it starts to work. But this is far from intuitive.
