grub-efi-amd64: GRand Unified Bootloader, version 2 (EFI-AMD64 version)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This is a dependency package for a version of GRUB that has been built for
 use with the EFI-AMD64 architecture, as used by Intel Macs (unless a BIOS
 interface has been activated). Installing this package indicates that this
 version of GRUB should be the active boot loader.

grub-efi-amd64-bin: GRand Unified Bootloader, version 2 (EFI-AMD64 modules)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This package contains GRUB modules that have been built for use with the
 EFI-AMD64 architecture, as used by Intel Macs (unless a BIOS interface has
 been activated). It can be installed in parallel with other flavours, but
 will not automatically install GRUB as the active boot loader nor
 automatically update grub.cfg on upgrade unless grub-efi-amd64 is also
 installed.

grub-efi-amd64-dbg: GRand Unified Bootloader, version 2 (EFI-AMD64 debug files)

 This package contains debugging files for grub-efi-amd64-bin. You only
 need these if you are trying to debug GRUB using its GDB stub.

grub-efi-arm64: GRand Unified Bootloader, version 2 (ARM64 UEFI version)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This is a dependency package for a version of GRUB that has been built for
 use on ARM64 systems with UEFI. Installing this package indicates that
 this version of GRUB should be the active boot loader.

grub-efi-arm64-bin: GRand Unified Bootloader, version 2 (ARM64 UEFI modules)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.

 This package contains GRUB modules that have been built for use on ARM64
 systems with UEFI. It can be installed in parallel with other flavours,
 but will not automatically install GRUB as the active boot loader nor
 automatically update grub.cfg on upgrade unless grub-efi-arm64 is also
 installed.

grub-efi-arm64-dbg: GRand Unified Bootloader, version 2 (ARM64 UEFI debug files)

 This package contains debugging files for grub-efi-arm64-bin. You only
 need these if you are trying to debug GRUB using its GDB stub.
