Bug#1007928: grub-installer: support for arm64 EBBR systems
Package: grub-installer
Version: 1.182
Hello,
On arm64 EBBR style systems with U-boot + EFI API the persistent
variable store can, unfortunately, be read-only when boot time services
have finished[1]. Meaning that Linux is unable to set EFI variables.
Would it be possible to please add logic for arm64 + EFI to re-attempt a
failed grub-install with the extra flags added:
--force-extra-removable --no-nvram
For reference, this was discussed briefly on debian-boot[2].
Also, unfortunately, the force-efi-extra-removable logic only employs
the following flag:
--force-extra-removable
So on arm64 EBBR systems the "expert mode" installation option doesn't
work either :-(. Could --no-nvram please be added to this option?
FWIW, for testing this I built a recent u-boot with qemu_64_defconfig
and passed the resultant u-boot.bin to qemu with "-bios u-boot.bin".
Also, I'm more than happy to quickly test grub-installer .udebs
Cheers!
