Hello, I've got the wip-ppc branch of Guix compiling unmodified on my Talos II. Since the POWER9 is backwards compatible with the PowerPC G4, it can run the existing bootstrap binaries for powerpc-linux. The binaries from http://flashner.co.il/guix/bootstrap/powerpc-linux/ have been verified working on my Talos II. I also plan to setup a mirror of those binaries.
