Failure grub-install: device.map missing - but this is unavailable in Arch Linux

[cmonty14]

Hi, the script is executing this command to install Grub2: sudo ${GRUB2_INSTALL} ${GRUB_TARGET} --boot-directory=${USBMNT}/boot ${USBDEV} or sudo grub-install --target=x86_64-efi --efi-directory=/mnt/tmp --removable --boot-directory=/mnt/tmp/boot /dev/sdd1

However, there's no device.map in /boot/grub/ on Arch Linux. And there's no grub-mkdevicemap to create it.

Please advise how to fix this issue?
