I did some tests (manually) with autoyast and autoyast2. I did few
installations of Tumbleweed on s390x with autoyast and autoyast2. I had some
issues to set a proper "environment": ftp server, http server, parmfile and so,
but at the end autoinstall worked. 

There were "partitioning errors", but after updating the "cloned" .xml file,
adding <dasd>...</dasd> section after the </bootloader>, e.g.

  <dasd t="map">
    <devices t="list">
      <listentry t="map">
        <channel>0.0.0150</channel>
        <diag t="boolean">false</diag>
        <format t="boolean">false</format>
      </listentry>
        <listentry t="map">
        <channel>0.0.0160</channel>
        <diag t="boolean">false</diag>
        <format t="boolean">false</format>
      </listentry>
  </devices>
    <format_unformatted t="boolean">false</format_unformatted>
  </dasd>

I didn't use serial consoles, I was using only the x3270 console. In the x3270
console you could see the very beginning of the IPL-ing or booting process. 

Might be few screenshots taken from x3270 "green screens" could help...
