+Subject: [PATCH] lib.sh: rm Ubuntu boot entry on EFI systems
+
+On EFI-enabled systems, grub-install from grub-efi-* package
+installs a boot entry named "ubuntu".
+
+MaaS relies on IPMI to set boot order to PXE first; however
+on systems with buggy firmware or without full IPMI support,
+that fails, leading to booting Ubuntu from hard disk instead.
+
+Work around this by clearing any previous Ubuntu boot entry
+from board flash, before starting a new baremetal deploy.
+
+NOTE: This only runs against nodes that are online from a
+previous deploy.
+
+Closes: ARMBAND-47
