<pre>While doing some work in trying ensure hostnames get set correctly on CoreOS I
found that running hostnamectl set-hostname would destroy the file
/etc/machine-info.
In this case the hostname "host-10-0-0-7" is the hostname assigned via DHCP.
The file /etc/machine-info was created by hand and the system was subsequently
rebooted.
[bharrington@leviathan-alticon-net coreos]$ ssh 192.168.1.202
