[buildarmimg] generic-efi device has no functuonal grub
The generic-efi
device currently just boots to a grub rescue shell.
I believe this is because the step where we create the grub.cfg config currently fails with a "No canonical path to /dev/loop2" error, when we run grub-mkconfig
inside the rootfs.
I've tried running the step from the host, but that results in all the hosts kernels getting probed and added to the rootfs config. Which is not what we want.
Good news is, this should be the last issue, before we have a working generic EFI based image.
