After playing with the autoyast process, I think I figured out how-to
convert from dhcp to static IP on a installed system. 

It's not pretty, but it works. :) Please keep in mind I just started
playing with autoyast a couple of weeks ago.

This is what I have in the networking section of the control file:

<networking>
     <nfs_server> 
      <nfs_exports config:type="list">
        <nfs_export> 
          <allowed config:type="list">
            <allowed_clients>@lab_nis(rw,sync)</allowed_clients>
          </allowed>
          <mountpoint>/local</mountpoint>
        </nfs_export>
      </nfs_exports>
      <start_nfsserver config:type="boolean">true</start_nfsserver>
    </nfs_server> 
    <dhcp_options> 
      <dhclient_client_id></dhclient_client_id>
      <dhclient_hostname_option></dhclient_hostname_option>
    </dhcp_options>
    <dns>
      <dhcp_hostname config:type="boolean">true</dhcp_hostname>
      <dhcp_resolv config:type="boolean">true</dhcp_resolv>
    </dns>
    <interfaces config:type="list">
      <interface> 
        <bootproto>dhcp</bootproto>
        <device>eth0</device>
        <startmode>onboot</startmode>
      </interface>
    </interfaces>
    <modules config:type="list">
    </modules>
    <routing>
      <ip_forward config:type="boolean">false</ip_forward>
    </routing>
  </networking>

Then I have the following in the post-scripts section:

<script>
<debug config:type="boolean">false</debug>
<feedback config:type="boolean">false</feedback>
<filename>staticIP</filename>
<interpreter>shell</interpreter>
<location></location>
<network_needed config:type="boolean">false</network_needed>

Subject: [opensuse-autoinstall] SuSE 10.1 + Converting from dhcp to
static IP

***Sending Message again, first message didn't seem to go through***

SuSE Version: 10.1
Install Method: PXEBOOT/DHCP 

Hello Everyone!

I was wondering if anyone had any suggestions on how-to convert from
dhcp-boot to static IP during the autoyast install?

Questions:
1) Should converting from dhcp-boot to static IP take place during
pre-scripts, or post-scripts?
2) When the install is initiated with dhcp, what file holds the
network/dhcp information during the install process?
3) Would it be practical to use commands such as ifconfig and netstat to
get the network information, and write to the
/etc/sysconfig/network/ifcfg-eth-id-$MAC and
/etc/sysconfig/network/routes files?

Observations:
I have noticed if a client is using dhcp, the package "NetworkManager"
is installed, and will manage the network settings for eth0. However, if
a client is using dhcp/NetworkManager, the NTP & NIS services will fail
to start during bootup. If I manually change the network settings to
static, NTP & NIS will start during bootup. 

Any help with this would be greatly appreciated. 

My best to you
