I am already using this image...
just connect a USB Harddrive... setup samba share or nfs share... copy a big amount of data to/from the harddrive... you will see that the device will reconnect as read only on a different device path...
This board, as it is right now, is not usable as a storage server... please prepare a functional kernel... if a device tree for kernel 4.x would be available, I am pretty sure the community would help to fix the rest...
