Anyway the rEFInd UEFI manager v0.14.0 doesn't show the Artix kernel icon at all somewhy with the below settings seeming to be nothing wrong
Code:
% cat boot/refind_linux.conf
"Artix" "root=UUID=362b39ad-6169-42bb-9c20-0e5fe5a2ac8e rw rootflags=subvol=Artix initrd=Artix\boot\initramfs-linux.img"
"Artix single user mode" "root=UUID=362b39ad-6169-42bb-9c20-0e5fe5a2ac8e rw rootflags=subvol=Artix initrd=Artix\boot\initramfs-linux.img single"
% cat etc/fstab
