Hi, thanks to systemd's predictable network interface names (http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterface...), I have no way to tell what my eth0 interface is actually going to be called ahead of time as it varies amongst different computers. Is there anyway to affect all available network interfaces with autoyast?
<networking>
        <interfaces config:type="list">
            <interface>
                <bootproto>dhcp</bootproto>
                <device>How do I make it affect all devices? Or at least  systemd's equivalent to eth0.</device>
                <startmode>onboot</startmode>
            </interface>
        </interfaces>
    </networking> 		 	   		  --
I put only localhost in the interfaces section:

    <interfaces config:type="list">
      <!-- leave out the systemd/udev named active device -->
      <interface>
        <broadcast>127.255.255.255</broadcast>
        <device>lo</device>
        <ipaddr>127.0.0.1</ipaddr>
        <netmask>255.0.0.0</netmask>
        <network>127.0.0.0</network>
        <prefixlen>8</prefixlen>
        <startmode>auto</startmode>
        <usercontrol>no</usercontrol>
      </interface>
    </interfaces>

This works out of the box.

For some servers I have an autoyast init script to give the interface a
static IP address.

I use the following line to get the device name:

act_iface=$(/sbin/ip link | grep '[1-9]*: en' | grep 'state UP' | awk
'{print $2}' | sed 's/://')

Best regards
Robert
