<div dir="auto">I know s390x I just need to know what a CentOS builder looks like. I can use ClefOS or RHEL to provide the bootstrap environment. When we first did 6.2 we boostrapped with rhel 6 and once the first ClefOS came out the other end we used it for
all subsequent builds. We used the three phase approach to get the end product. </div>

<div class="PlainText">Hi, Jim<br>
<br>
The resources is not a problem. I had allocated two raw z/VMs at<br>
Marist in 2018 and the developer was working on it until told to stop.<br>
<br>
The challenge is a person knowledgeable with CentOS bootstrap and s390x.<br>
<br>
Thanks, David<br>
