Hello, I am running machinery 1.20.0 (I suppose the latest). I do inspect + export-kiwi. In config.xml I see the following: <type image="vmx" filesystem="ext3" installiso="true" boot="vmxboot/suse-leap42.1" format="qcow2" bootloader="grub2"/> whereas my target filesystem is btrfs. Is it just unsupported, or I am doing it wrong?
