// You need to have a alpine image @ /root/sandbox/image to run this example
// You will also need a command named "loop" @ /bin/loop inside the root image.
// The source of loop can be found @ https://gist.githubusercontent.com/szdytom/ec2d99a41477787a8c85f6ec73af4ca2/raw/54fb722cb3ed60ef902573ee2ce503d8760ec723/loop.c
// You need to complie it using option --static or install musl libc for alpine linux uses it.
