The powerpc platform has always been interesting, but hard to get and while we’ve had some levels of interest in the past, either I struggled to find the hardware to bootstrap the builds, or we were unable to get enough communication going to bring the community of contributors together to kick things off. Now as we work through the mechnics of building and delivering CentOS-7 on x86, we again have the opportunity to try and see if there is a willing, contributor community that can come form up a PPC SIG in CentOS.
We do have some resources ( compute + network + mirror ) to make the backend side of things happen, and the folks at OSUOSL.org have offered us some capacity on their community powerpc builder resources to help as well.
