If the VPN tunnel can't be established because the peer/server isn't available at the moment, the vtun interface never becomes registered with the kernel, which makes this code never end, and the commit hangs:
**interface-openvpn.py:**
```
while openvpn['intf'] not in interfaces():
sleep(0.250) # 250ms
Interface(openvpn['intf']).set_alias(openvpn['description'])
```
Perhaps add a form of timeout?
