1. Create new folder to hold EFISTUB
# mkdir -p /boot/EFI/arch

2. Combine intel-ucode and initramfs into single bin file
# cat /boot/intel-ucode.img /boot/initramfs-linux-dracut.img > /boot/EFI/arch/initrd.bin

3. Copy (or just create) file with current command line options to be passed to .efi
#  cat /proc/cmdline | sudo tee /boot/cmdline-linux.txt

4. Use objcopy to create .efi output file (last argument, /boot/EFI/arch/linux-dracut.efi)
##/EFI/Linux is searched for specially prepared kernel files, which bundle the kernel, the init RAM disk (initrd), the kernel command line and /etc/os-release into one single file. This file can be easily signed for secure boot.
##Note: systemd-boot requires that the os-release file contain either VERSION_ID or BUILD_ID to generate an ID and automatically add the entry, which the Arch os-release does not. Either maintain your own copy with one of them, or make your bundling script generate it automatically.
##Optionally sign the linux.efi file produced above.
##Copy linux.efi into esp/EFI/Linux. 

# objcopy /
--add-section .osrel="/usr/lib/os-release" --change-section-vma .osrel=0x20000 /
--add-section .cmdline="/boot/cmdline-linux.txt" --change-section-vma .cmdline=0x30000 /
--add-section .linux="/boot/vmlinuz-linux" --change-section-vma .linux=0x40000 /
--add-section .initrd="/boot/EFI/arch/initrd.bin" --change-section-vma .initrd=0x3000000 /
/usr/lib/systemd/boot/efi/linuxx64.efi.stub /boot/EFI/arch/linux-dracut.efi

5. Use efibootmgr to confirm or add as needed
# efibootmgr --verbose
# efibootmgr /dev/sda --part 1 --create --label "Arch Linux Dracut" --loader /EFI/arch/linux-dracut.efi --verbose
