Hi Serge,

thank you for your reply, your suggested solution (using setns to switch
the namespace) is really interesting. How do you want to proceed? We can
use the program you wrote or maybe we can follow the same path using,
e.g., Python/ctypes or Go? Should we instead consider waiting for
lxc-attach to be ready?
