Source: edk2 Version: 2023.02-2 Severity: wishlist Tags: patch Dear Maintainer,
On installation of an architecture-appropriate efi-shell-XXX package, please copy the shell into the EFI partition and configure grub2 to have a boot menu entry to enter that shell. I attach an example grup config file for aarch64, which works if dropped into /etc/grub.d/35_efi-shell-aarch64 and the shell has been installed as /boot/efi/EFI/tianocore/shellaa64.efi The architecture test in the grub config file is probably not exactly the best one; feel free to improve so that it works when running e.g. an armfh or 32-bit arm Debian port on an aarch64-able machine. For other architectures, adapt the architecture test. Maybe you can generate the file for each architecture from a template where the only change is the architecture test. -- System Information: Debian Release: 12.0 APT prefers testing-security APT policy: (600, 'testing-security'), (600, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: arm64 (aarch64) Kernel: Linux 6.2.0 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
