This seems to come from /etc/hosts not being populated with the devices' hostname, but this happens on normal docker. It's not clear if this is a bug in the supervisor or balenaEngine (or even the OS itself).

Either way, this can be solved on the supervisor side by adding <hostname>:127.0.0.1 to the extraHosts array on a container with host networking.
