We use autoyast templates with a static network configuration like:

==
        <interfaces config:type="list">
            <interface>
                <bootproto>static</bootproto>
                <device>eth0</device>
                <ipaddr><?=$ip ?></ipaddr>
                <netmask><?=$netmask ?></netmask>
                <startmode>auto</startmode>
                <usercontrol>no</usercontrol>
            </interface>
        </interfaces>

        <routing>
           <ip_forward config:type="boolean">false</ip_forward>
           <routes config:type="list">
             <route>
               <destination>default</destination>
               <device>-</device>
               <gateway><?=$gateway ?></gateway>
               <netmask>-</netmask>
             </route>
           </routes>
         </routing>

        <net-udev config:type="list">
            <rule>
              <name>eth0</name>
              <rule>ATTR{address}</rule>
              <value><?=$mac ?></value>
            </rule>
        </net-udev>

Works fine with OpenSuse 13.1
But the net-udev part is broken in OpenSuse 13.2

There is no longer a persistent network rules file generated in
/etc/udev/rules.d
And after installation OpenSuse creates the network interface eno1 (running
DHCP) instead of eth0 (with static configuration) like specified, resulting in
a broken network configuration.

This is a major issue as it prevents dedicated server providers (which use
static network configurations) from performing autoyast installations.
