Comment # 13 on bug 1095383 from Marius Tomaschewski

Wicked changed to use to a newer RFC to create it's dhcp client identity
(required e.g. to make dns updates for ipv4 and ipv6 at the same time).
See https://tools.ietf.org/html/rfc4361#section-6.1 for more details.

Unfortunately, some dhcp-servers are using e.g. static leases bound to
the client-id, and do not provide any answer otherwise or also, cannot
handle the new client id properly (e.g. too long).

Thomas,

can you try if you it works for you when you boot the install ISO with the
following parameters?

   ifcfg=$MAC=dhcp,DHCLIENT_CLIENT_ID=01:$MAC

where "$MAC" is the mac address of the network card you want to use, e.g.

   ifcfg=52:54:00:8d:64:18=dhcp,DHCLIENT_CLIENT_ID=01:52:54:00:8d:64:18

The new client-id default can be also reverted by adding the following
config to /etc/wicked/local.xml:

  <config>
    <addrconf>
      <dhcp4>
        <create-cid>rfc2132</create-cid>
      </dhcp4>
    </addrconf>
  </config>
