Hello We are using diskimage-builder to generate an ARM UEFI ISO for the Akraino REC blueprint. We have exactly the same problem documented here: https://bugs.launchpad.net/diskimage-builder/+bug/1851516 When our script uses grub2-mkconfig, grub.cfg is not relocated as shown grub2-mkconfig -0 /boot/efi/EFI/centos/grub.cfg The image is built with /boot/grub2/grub.cfg instead. Any thoughts on a work around for this?
