Sebastian...

First I need to warn you that I'm just learning LXC myself over the last 3
months but I've found alot of good information and I think if I understand what
you are asking.. that it can be done with bind.

Look at this web page's script and search for

"#configure shared directory in containers"

https://github.com/chmouel/my-lxc-setup/blob/master/install.sh

I've seen other examples and I know I've book-marked them but this was the first
I spotted so I figured I throw it out to you to see if it helps?
