This seems like a tricky one, but I noticed that I can't use "docker run -v ..." with Docker 0.8 on OS X with boot2docker.

Also, I get no error message. My docker container just fails to run properly because paths are missing. At minimum, docker run should fail with an "unsupported on OS X" error message.

But ideally, since boot2docker in VirtualBox is on a different (virtual) machine than the OS X host and we can't simply bind mount between them, perhaps a FUSE filesystem can be mounted in the Linux VM that forwards back to the OS X host.
