Title:
  \EFI\BOOT\BOOTX64.EFI unable to find GRUBX64.EFI

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  Machines managed by MAAS are configured to always netboot. When an
  operating system is deployed MAAS chainloads the local boot loader[1].
  As per the 3.5.1.1 of UEFI spec[2] \EFI\BOOT\BOOTX64.EFI is attempted
  first. \EFI\BOOT\BOOTX64.EFI fails to find GRUBX64.efi as it is
  located in \EFI\UBUNTU(see screenshot).
