Hangs after "Initialization Sequence Completed"

[edent]

I'm running sudo ~/git/namespaced-openvpn/namespaced-openvpn --config my.conf

It goes through all the expected startup actions, gets to "Initialization Sequence Completed" and then.... nothing! I left it for a couple of minutes, but nothing happened.

Is there any way to debug this?
