No. I'm not familiar with LXC internals but i assumed that a container setup that specifies mounts has its own mount namespace? If this is true then the container has its own private view of the filesystem (different from the host), and you can not safely copy/inherit filesystem state like the cwd from the host.

The filesystem inside a container should *always* have a valid cwd (just like the filesystem of the host). I will be very happy with a lxc.chdir option! (I like the name, its better than lxc.mount.cwd) Will probably use it in all my lxc-execute configurations...
