Installing from USB: "You must specify the filesystem type for loop0"

Hi there,
I am trying to install Arch to my old MacPro1,1 using a live-USB stick with a fresh copy of archlinux-dual.iso

As of the Mac's old firmware, I need to boot from USB using refind to boot grub.
My grub.cfg on the USB-stick looks like this (as stated in https://wiki.archlinux.org/index.php/Mu … rch_Linux) and points to the iso-files at the root of the USB-stick:

menuentry '[loopback]archlinux.iso' {
	set isofile='/archlinux.iso'
	loopback loop $isofile
	linux (loop)/arch/boot/x86_64/vmlinuz archisodevice=/dev/loop0 img_dev=$imgdevpath img_loop=$isofile earlymodules=loop video=efifb fbdev noefi single
	initrd (loop)/arch/boot/x86_64/archiso.img
}

GRUB boots into the iso file.

My problem is, that systemd gives the following error while booting from USB:

Mounting /dev/loop0 to /run/archiso/bootmnt
MOUNT: You must specify the filesystem type
ERROR: Failed to mount /dev/loop0
Falling back to interactive prompt

My question is how to solve this error.
where and how can I specify the filesystem type for loop0 ?

Greetings
