I am using an image based on the v4.0.0.0 variant but I needed to rebuild
it to overcome some other issues with the image. What you listed does work
for me. If the link is not active, looking at the output of `ip addr` will
not show any inet address(es). I don't see any obvious typos/differences
between what you provided and what I am using but including the contents
just to be safe. As far as I know the name should not make any difference
provided it ends with `.network`.
