[SOLVED] fwupd does not recognize EFI parition mounted at /boot

Today I tried to run fwupdmgr and got the error:

Unable to determine EFI system partition location, See https://github.com/hughsie/fwupd/wiki/Determining-EFI-system-partition-location

Which was baffeling, because, the EFI partition was mounted unter /boot, formatted as FAT32 (vfat) marked as ef00 and was not corrupt according to fsck.
After half an hour of try-and-error I found out, that fwupdmgr does not recognize the partition when mounted at /boot.
I could. however run it by unmounting it, creating /boot/efi and mounting it there.
In case you wonder, here's the journal:

This, however is a bad solution for me, since I use EFISTUB to boot the kernel via EFI directly.
Thus, I need the kernel and initramfs on the EFI partition (and not much else), so mounting the EFI partition to /boot/efi will require me to manually copy the kernel image, initramfs and microcode image to /boot/efi after each upgrade.
While this is certainly possible via pacman hooks, it seems like an unnecessary hassle to me.
Is there a way to tell fwupdmgr to look for the EFI partition under /boot?

I could. however run it by unmounting it, creating /boot/efi and mounting it there.

Does directory /EFI exist on the EFI partition? https://github.com/fwupd/fwupd/blob/c73 … #L313-L314

	/* /boot is a special case because systemd sandboxing marks
	 * it read-only, but we need to write to /boot/EFI

No. It did not. After creating the directory and restarting fwupd.service the error message is gone.
Unfortunately I cannot test, whether it works as there are currently no updates available.
