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.

Hi, Jim

The resources is not a problem.  I had allocated two raw z/VMs at
Marist in 2018 and the developer was working on it until told to stop.

The challenge is a person knowledgeable with CentOS bootstrap and s390x.

Thanks, David
