Description Dmitry Rozhkov 2017-05-29 10:50:35 UTC 
The command

> ping `hostname`

seems to work in Refkit on real hardware, but it fails to resolve the result of the `hostname` command when running in QEMU. Which makes testing ROS nodes inconvenient because ROS tests accessibility of `hostname` (the default name of a master ROS node) before launching any node.

The file /etc/nsswitch.conf contains the line

> hosts:          files myhostname  dns

So the culprit is a malfunction in the myhostname plugin most probably.
