Package: grub-efi-arm64 Version: 2.06-5 Severity: wishlist X-Debbugs-Cc: a...@kernel.org
Dear Maintainer, Linux 6.1 and later implement a EFI bootable compressed format called zboot, which does not carry the 'arm64 bare metal boot' magic number because it is EFI-only and cannot be booted in bare metal mode unless the bare metal loader knows how to decode the header and perform the decompression itself. None of this is relevant to GRUB, as it is pure EFI based on arm64. However, it used to check the magic number nonetheless, rejecting these EFI zboot images for no good reason. This is fixed in GRUB upstream by https://git.savannah.gnu.org/cgit/grub.git/commit/?id=69edb31205602c29293a8c6e67363bba2a4a1e66 Please consider this change for backporting to Debian's GRUB so arm64 builds can boot the EFI zboot images. Kind regards and merry christmas,
