Out of curiosity what does a typical c7-x86_64 builder look like for cpu, memory, and disk?

I think 2-4x f19-ppc64 BE builders with 2-4 cores, 8GB of memory and 20-40GB of disk should suffice for now.

And I only need 1x f21-ppc64le LE builder with 4 cores, 8GB of memory and 50-100GB of disk if you spare it for now. A lot of the initial toolchain building, and rpm wrangling has to happen in a persistent mockroot that grows with every ppc64le rpm that gets built. Once enough c7 ppc64le rpms exist, that builder can go away and we can do some LE parallel builds atop c7-ppc64le builders with less /var/lib/mock disk space.
