From: Karanbir Singh <kbsingh at centos.org> To: David Edelsohn <edelsohn at us.ibm.com> Date: 05/17/2018 11:17 PM Subject: Re: CentOS on Z-Series Hi David, We wont need ClefOS to do the bootstrap, we'd want to do it the same way as we did the power bringup and the arm-server etc just to keep the baseline intact and work from there up. ----- The plan from the IBMer who had bootstrapped CentOS on PPC64LE Linux was: I just spoke a bit with Jim Perrins (Evolution on irc) and got the go ahead to use ClefOS to speed up the bootstrap. I think I’ll stop asking questions and get to work quietly before Karanbir Singh tells me I have to use old Fedora 19 s390x rpms to bootstrap and build everything from CentOS 7.0 -> 7.1 -> 7.2 -> 7.3 -> 7.4 -> 7.5 I will build CentOS 7.5.1804 s390x/s390 will a small backing of ClefOS rpms, and then rebuild CentOS 7.5.1804 s390x/s390 cleanly with itself. At some point I”ll need to get the LinuxOne VMs reinstalled with my CentOS code for the final rebuild and then turn things over to CentOS guys to gpg sign and publish. ----- The IBMer then was instructed to not help Z. And the CentOS work never was staffed within IBM. - David On Wed, Mar 18, 2020 at 3:49 AM FuLong Wang <fulwang at linux.vnet.ibm.com> wrote: > > Hello Everyone, > > > I'm from IBM China Development Team and I'm working on a new initiative that plan to enable a "minimized" or "full" CentOS operating system on IBM LinuxONE / IBM System Z (s390x architect). > > The reason why we start this topic is we are trying to contribute to the RDO community with our OpenStack build on LInuxONE. > We have successfully finished the build job for OpenStack Train Version on LinuxONE and passed the basic function verification tests recently. > Now, we already have a link for worldwide users & fans to reference for their needs. > For "official official" contributing to the RDO community, community admin stated that a TripleO CI env is a must for community release criteria and > the OpenStack packages need to be built in the CentOS build system which run on s390x arch. > > > So, we turn to here for help, we know CentOS community ever had releases for s390x arch but for whatever reasons finally stopped for update. > We want to take this opportunity to enable it up again and therefore > want to know about the overall processes, skills required, hardware requirements, manpowers and duration estimated and which parts need IBM's team's input, etc. > > Our target is to enable at least a "minimized" CentOS (which can support the OpenStack CI work), is there a SIG fit for this purpose? or a "full" CentOS with default feature sets. > > > Could anybody kindly give us some clue to start this journey? > > > Thanks everyone in advance! > > > The Howto of OpenStack Train Installation on IBM LinuxONE had been merged to the RDO official website. > > https://www.rdoproject.org/install/ > > > > -- > FuLong Wang > fulong.wang at cn.ibm.com > IBM China Systems Lab, Beijing, China > _______________________________________________ > > _______________________________________________ > CentOS-devel mailing list > CentOS-devel at centos.org > https://lists.centos.org/mailman/listinfo/centos-devel
