fuel-astute: Erase EFI boot entry on EFI systems
On EFI-enabled systemd, grub-install from grub-efi-* package installs a boot entry named "ubuntu". Since this boot entry is saved in board flash memory, erasing the MBR bootloader code and/or partition signature will not clear the ubuntu boot entry, leaving it pointing to a loader on the ESP (EFI System Partition) that will try to load the kernel/initrd from an erased partition. In Fuel 8.0, the whole disk was erased, so the ubuntu EFI boot entry was skipped due to missing ESP, while for Fuel 9.0 and above we have to explicitly remove it to keep the system in a sane state. Note: efibootmgr is installed automatically on EFI systems as a dependency of grub-efi-*.
