UP^2 Arch Linux Installation: Using UEFI Directly: efibootmgr example doesn't appear to work?

Has anyone else run into problems here?

Using UEFI directly

efibootmgr

I found the example command for efibootmgr to be problematic. I couldn't get it to work for Arch Linux. After much trial and error the solution that actually worked is a follows. Compare the original command with the solution.

The original command...

# efibootmgr --disk /dev/sdX --part Y --create --label "Arch Linux" --loader /vmlinuz-linux --unicode 'root=PARTUUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw initrd=\initramfs-linux.img' --verbose

Solution: Replacing the above command with...

# efibootmgr --disk /dev/sdX --part Y --create --label "Arch Linux" --loader /vmlinuz-linux --unicode 'root=/dev/sdX rw initrd=\initramfs-linux.img' --verbose

Where --disk /dev/sdX... is the EFI boot partition.
Where root=/dev/sdX... is the root partition of the Arch Linux installation.

@smackoz I run Arch on my UP Squared and Boards. With systemd-boot, I do recall the UUID method not working as well, and resorted to using device paths.

Remember, the Arch wiki, while awesome with details, is usually written by a person that got it working their way.

I have 100s of edits and a few new pages written on the Arch Wiki over the years. Feel free to add the alternative device path option to that page as I am sure it might help others down the road.

Personally, I run Xen hypervisor on mine to EFI boot from.

Feel free to browse my Arch Linux bootstrap scripts I use for UP^2 devices. (Need to specify the mmc path, instead of sdX).

Thanks. Was wondering if I'd missed something or it was the flavour of these UP^2 boards.

Hi smackoz and eduncan911: I hope you don't mind me not opening a new thread, could you let me know about your experience of running Arch on the up squared? Is there anything I need to pay attention to apart from those EFI boot parameters? Would you recommend this device for using with Arch?
