Comment 46 for bug 1561250

This change will be backported to xenial, but only once we've heard that we've actually fixed it.

Robert, GGeorg, LoOoD, does the box I provided fix the issue?

(Also, Robert, I really do understand the frustration but this wasn't actually as simple a fix as you seem to think; Vagrant boxes should have their hostname set dynamically at boot, which means you can't simply write out the hostname to /etc/hosts during the image build process. And when you add in to this the fact that a lot of behaviour that is clearly expected of Vagrant boxes isn't actually documented anywhere[0], any fix becomes time-consuming as you have to try and work out what the expected behaviour is by looking at other Vagrant boxes.)
