Instead of writing to a temporary file and deleting it, use the null block driver in qemu to throw it away.
This commit isn't quite right (although working) because certain places in the code expect target_file to be a real file. eg We are calling 'du' on the target file resulting in this non-fatal message: du: cannot access 'json:{ "file.driver": "null-co", "file.size": "1E" }': No such file or directory Need to think about this a bit.
