grub

[Gerard ROBIN <g.robin3@free.fr>]

Hello,
Here is the result of the command: dpkg -l grub (with Trixie)

ii  grub-common                 2.12-9       amd64      GRand Unified Bootloader (common files)
ii  grub-efi-amd64              2.12-9       amd64      GRand Unified Bootloader, version 2 (EFI-AMD64 version)
ii  grub-efi-amd64-bin          2.12-9       amd64      GRand Unified Bootloader, version 2 (EFI-AMD64 modules)
ii  grub-efi-amd64-signed       1+2.12+9     amd64      GRand Unified Bootloader, version 2 (amd64 UEFI signed by Debian)
ii  grub-efi-amd64-unsigned     2.12-9       amd64      GRand Unified Bootloader, version 2 (EFI-AMD64 images)
ii  grub2-common                2.12-9       amd64      GRand Unified Bootloader (common files for version 2)

Some packages are redundant; what is their purpose?
If some are useless, can they be removed?
For example, what is the use of having:

grub-efi-amd64,
grub-efi-amd64-signed,
grub-efi-amd64-unsigned 

Which one is actually used at startup?

Thanks.
