I'm happy to provide assistance, I encourage GNU Guix developers to join=20 #talos-workstation on Freenode's IRC, we have a friendly active=20 community that is always happy to help on POWER9 matters. dftxbs3e On 11/28/19 1:50 AM, Tobias Geerinckx-Rice wrote: > Fellow Guix, > > The Guix sysadmins are considering buying shiny hardware for the=20 > ci.guix.gnu.org build farm, and it would be awesome if that included=20 > our first POWER9 machine(s)! > > However, few (if any) Guixers have any hands-on experience with this=20 > architecture, let alone buying and installing whole systems.
