Unfortunately no :( It was only 3 items when we first looks at it, so I 
just kept one in my head. The list was

1. multiple mount namespaces (done)
2. external mounts (--ext-mount-map patches on the mailing list)
3. the mentioned reattach thing (--exec-cmd merged, waiting for the LXC part)

Yes, of course. Native C/R is one of the must-have requirements.

Thanks,
