Tootfinder

I upgraded my backup Scaleway VM from debian 11 to debian 13 (trixie); 11->12 went easily; but 12->13 was a fight. First off an old motd script (scw-metadata) stopped me logging in; and then after a reboot it landed at grub-rescue> complaining about a messing symbol ('grub_is_lockdown') - that turned out to be that there was an old fallback Grub in /boot/efi/EFI/BOOT/BOOTX64.EFI which is what it was booting from rather than the EFI/debian one
