[Bug 1867387] [NEW] \EFI\BOOT\BOOTX64.EFI unable to find GRUBX64.EFI

[Lee Trager]

Public bug reported:

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).
