+Subject: [PATCH] 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-*.
+
+Closes: ARMBAND-47
