[atomic-devel] Shared mounts in Atomic Host

[Dusty Mabe <dusty dustymabe com>]

I am using the updates-testing f23 atomic host that has docker 1.10. I
want to have a shared mount between the host and a docker container.

I'm trying to do it but I keep getting an error

```
[vagrant vanilla-f23atomic ~]$ rpm -q docker
docker-1.10.2-6.git0f5ac89.fc23.x86_64
[vagrant vanilla-f23atomic ~]$ sudo atomic host status
  TIMESTAMP (UTC)         VERSION   ID             OSNAME            REFSPEC

[vagrant vanilla-f23atomic ~]$ sudo mount --make-shared /                                                                                                                                            
[vagrant vanilla-f23atomic ~]$ sudo docker run -it --privileged --rm -v /tmp/sharedfolder:/tmp/sharedfolder:shared sshfs /bin/bash  
docker: Error response from daemon: Cannot start container 7e99752dd8f2812a7d7acaa58594504be936b6f37aa77b6521a7098450343837: Path /tmp/sharedfolder is mounted on /sysroot but it is not a shared mount..
```

I think this should work because this commit is in docker 1.10:
https://github.com/docker/docker/pull/17034/commits

Am I doing something wrong?
