Dear Maintainer,

I created a new container, with the busybox template.  My network has a
dhcp server on it serving ipv4 addresses, and uses router advertisement
for ipv6 ones.  I can see from the console logs and my dhcp server logs
that I am assigned an ipv4 address, but ip addr show or ifconfig from
inside the container don't have the address.
