Docker image for installing 9p modules into boot2docker

Can be built with ./build.sh.

When connected to boot2docker hosted docker server

docker run --rm --privileged -v /etc:/data xforty/boot2docker-9p

Alternatively, you can run without privileged and it will just place the compiled kernel modules in /etc/9p

When built, this will use the xforty/boot2docker-9p-builder image to pre-build kernel modules for different versions of boot2docker.

When run, boot2docker-9p will detect the boot2docker version and either load a pre-built kernel module in, or build a new one on the fly if one isn't found.
