Today we have heard from KB that he is stepping down from the CentOS Board of Directors.

On behalf of the Board, I want to thank KB for his years of leadership. His work on the project, and in the community, has made the world a better place in tangible ways that affect millions of sysadmins on a daily basis, and that's hard to measure or quantify.

On a personal note, I've appreciated his advice, insight, and mentorship as I took the reins of the Community Manager position. His stories and introductions paved the way for success in a role that has been very rewarding and a lot of fun.

I know that many of you have stories about how KB has influenced your life - professional and personal - and we'd love to hear them. We encourage you to send them to the centos-devel mailing list in the coming days, or post them in the comments here. I'm sure that you, like myself and the Board, wish him well as he moves on to other challenges in the coming years.

On a governance side, you should be thinking of who you might wish to nominate to fill his seat on the board, and look for details in the coming days, on the centos-devel mailing list, of how that process will work.

The CentOS Automotive SIG launched in August following approval from the CentOS Board in July. This SIG, instigated by Red Hat and open to all, is meant to be a neutral public space for collaboration between third parties interested in open development of software targeted at in-vehicle automotive use cases, and to provide automotive projects and the resulting CentOS variant with build and test infrastructure. The goal of the SIG is to provide an open-source home for RHEL-oriented automotive work, and to attract and encourage open development of automotive software between commercial and non-commercial partners.

To that end, this SIG will have three primary functions:

  • Create open source software related to automotive
  • Incorporate upstream projects related to automotive
  • Build and curate a CentOS variant for Automotive as a proof of concept and reference design for an in-vehicle automotive OS

Over the next few months, the primary goals are to build awareness and participation through outreach and public meetings, to create an initial Contribution Guide, and to generate a working manifest as well as initial builds for the CentOS variant. Work is being done to set up the build & test infrastructure using GitLab. More information on this infrastructure and how to access it will be provided as it matures.

The SIG held its first meeting with 34 attendees from a variety of organizations, including some automotive OEMs and tier-1 suppliers. Meetings are held every 4 weeks online, alternating every 2 weeks with an informal "office hours" discussion call. The meeting times are currently somewhat fluid and meetings move around a bit, as we want to accommodate everyone who can possibly make it. Anyone is welcome to attend, participate, and ask questions, and we encourage everyone to join the mailing list and to visit the #centos-automotive IRC channel on

We hope to see you at the next meeting!


Here's an overview of the news for October.


The SCLo SIG aims to provide Software Collections packages from Red Hat and community for the CentOS ecosystem.

For details about what Software Collections are, visit <>.


No changes in membership since last report. We are always looking for new members.

Health and activity

The SIG tries to follow the upstream releases as closely as possible;
any new releases are usually available within 2 weeks of the upstream release.

With the Software Collections being phased out in favor of modules in CentOS 8
and beyond, it is expected that this SIG will also be gradually becoming
less and less relevant, so expect the activity to gradually vanish.

The SIG activity is currently driven by a single person (jstanek).
That means that even if the released packages are being rebuilt within
a reasonable timeframe, other activities are falling by the wayside.
For example, the <> website has outdated information
about specific collections, and several already released ones are not documented there at all.
Any volunteers from the community are very welcome here.

Kmods SIG

This report covers work that happened since last report. The previous report can be found here.


Packaging and maintaining kernel modules for CentOS Stream.

Membership Update

No SIG members have been added since last report.

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute.

New Packages

No packages have been released yet due to missing mechanism to sign kernel modules. Some non-signed packages are already available in testing:

  • exFAT
  • WireGuard
  • SCSI controllers
  • P/SATA controllers
  • Network controllers
  • Rebuilds of kernel modules with Red Hat specific restrictions removed to restore support for deprecated adapters


To enable the main testing repository run the following commands:

  • dnf install centos-kmods-release
  • dnf config-manager --set-disabled centos-kmods
  • dnf config-manager --set-enabled centos-kmods-testing


To enable the testing repository for kernel module rebuilds you need to run in addition:

  • dnf install centos-kmods-release-rebuild
  • dnf config-manager --set-disabled centos-kmods-rebuild
  • dnf config-manager --set-enabled centos-kmods-rebuild-testing


Please report any issues with these packages in the corresponding project on or here in case the issue is not related to a particular package.

Health and Activity

The Kmods SIG maintains a healthy development pace.


Regular meetings are scheduled every two weeks (on even weeks) on Monday 1500 UTC in #centos-meeting. Everyone is welcome to join!

You can also get in touch with SIG members at any time in #centos-kmods.

Conference talks

An introductory talk to the Kmods SIG is scheduled for the October 2021 Online Dojo.

Roadmap Decisions

  • Support RHEL: The SIG agreed to also provide packages for RHEL. For now these are built against CentOS Linux 8. In the future it is planned to use RHEL buildroots once available in CBS.

Open Issues

  • Signing kernel modules: This requires collaboration and further discussion with Infra SIG. Especially about how to securely store a SIG specific key that can be used in CBS, but is not accessible by any unauthorized person.
  • Driver Disks: The SIG would like to provide Driver Disks required to install CentOS Stream on unsupported hardware. It is currently unknown how this can be best achieved in CBS.

Issues for the Board

We have no issues to bring to the board’s attention at this time.

It hardly seems possible that it’s already October. September (and the first few days of October) was very busy in CentOS news.


We had our first in-person event in almost two years, last week in Seattle, and we have two upcoming events.

October CentOS Dojo

Later this week we will be holding the October CentOS Dojo online.

This dojo will feature an AMA (ask me anything) session with the board of directors, and 9 technical sessions on topics ranging from EPEL to Automotive Linux to Modules.

Full details, including the schedule and free registration, are available on the CentOS Wiki.

Open Source Summit

Last week in Seattle, the Linux Foundation held Open Source Summit. CentOS had a presence there at the Red Hat booth. Thanks to all of you who dropped by with questions, or just to chat. We look forward to seeing all of you at more events in the coming months.

All Things Open

We hope you’ll come see us at All Things Open, two weeks from now in Raleigh, North Carolina. We’ll once again be at the Red Hat booth, where we’ll be talking about CentOS Stream and our various CentOS SIGs.

Fedora Linux 35 Release Party

Our friends over in the Fedora project have released Fedora Linux 35 Beta, and will release the GA very soon. They’ve invited us to join them at their release party on November 12th, to celebrate another great release.

Project News

Build for CentOS Stream 9

On September 3rd, Fabian announced that SIGs can now request a 9s tag in order to build against/for CentOS Stream 9. The full details of this are available on the centos-devel mailing list


Pat started a very interesting discussion on centos-devel this week about the possibility of making dnf automatic a default in Stream 9.

Please do read the discussion so far, and chime in if you have an opinion on this important decision.

Hyperscale Live DVDs

Neal has announced new LiveDVD images from the Hyperscale SIG. GNOME and KDE variants are available. Details are available in this thread.

The new site was announced a few days ago. This site will be a place where SIGs can publish documentation sourced out of a Git repo. If your SIG wants to take advantage of this new resource, please see the thread on centos-devel for details.

Board of Directors September meeting minutes

The minutes from the September Board of Diretors meeting have been posted to the blog.

I’d like to remind you that Board meetings are now public, and you’re encouraged to attend if you have any interest in how the project is governed. Watch the centos-devel mailing list for the announcement of the next board meeting.

The board meets on the second Wednesday of each month (That’s October 13th this month) at 20:00 UTC.

SIG Reports

CentOS Special Interest Groups (SIGs) are the best place to get involved in the CentOS Project, in the area of your interest. This month we have reports from four SIGs, and also some notes from the CPE (Community Platform Engineering) team.

Get Involved

There’s a number of places where you can get involved around the CentOS community.

CentOS Stream Contributions

Contributing changes to CentOS Stream is the way to influence not only future releases of CentOS Stream itself, but also Red Hat Enterprise Linux (RHEL) and the various downstream rebuild projects that derive from RHEL. See the contributor’s guide for details on how to get onboarded and contribute your first change.

SIG meetings

Each of our Special Interest Groups has regular meetings where you can find out what’s happening in the SIG, and where you can get involved.

The full meeting schedule is on the CentOS website. Most meetings happen in #centos-meeting on the IRC network.


Each month, we send out this newsletter to the centos-newsletter mailing list, as well as various other places. We always need more help with this effort, including gathering important stories, writing the newsletter itself, and providing translations. If you’d like to get involved, please subscribe to the centos-promo mailing list and introduce yourself.

Work on each newsletter begins as soon as the previous one is sent out, so now is the perfect time to get involved.

Test and report

Perhaps the most important part of the CentOS community is all of the users. Installing CentOS Linux or CentOS Stream, using it, and reporting about your experience, is central to making it better for everyone.

Additional detail about where and how to report problems may be found on the ReportBugs page in the wiki.

Stay in Touch

There’s many ways to stay in touch with the CentOS community.

Like many open source projects, the most important place is the various mailing lists. The most important of these are the list and the centos-devel list, which are focused on user support and developer interactions, respectively.

We have a presence on several social media platforms, including TwitterFacebook, and Reddit.

And the CentOS Forums are another place where there’s an active community, asking and answering questions on a variety of CentOS-related topics.

You can find the discussion forum that’s best suited to your preferred communication style.

As always, thanks for being part of the CentOS Community.

Rich, for the CentOS Project

This report covers work that happened between July 2nd and October 1st. For previous work, see the 2021Q2 report.


The Hyperscale SIG focuses on enabling CentOS Stream deployment on large-scale infrastructures and facilitating collaboration on packages and tooling.

Membership update

Since the last update, the SIG gained three new members (Chris Murphy, Omar Sandoval and Benjamin Kircher).

We welcome anybody that’s interested and willing to do work within the scope of the SIG to join and contribute. See the membership section on the wiki for the current members list and how to join.

Releases and Packages

Unless otherwise specified, packages are available in our main repository, which can be enabled with dnf install centos-hyperscale-release. Please report any issues with these packages on our package-bugs tracker.


In addition to the wiki, we now have a set of user documentation available on This is still a work in progress, and we’d welcome feedback and any contributions.


Our most recent backport of systemd is version 249 based on the Fedora packaging. This release includes improvements and new features across all of the various systemd daemons and tools. Our latest version also backports upstream patches to support additional systemd link file configurations, such as those for for RX/TX coalescing and knobs for NIC features related to hardware acceleration.

Following Fedora’s lead, we’ve also split systemd-networkd and systemd-resolved into separate subpackages. Both are included as optional packages when installing or upgrading systemd.


We have updated our btrfs-progs package to v5.13.1 and fixed a bug in our patch disabling RAID 5/6 in btrfs balance.


We used to ship a non-modular version of the LLVM 12 compiler suite. This has since become part of CentOS Stream 8 proper, so we have retired our build as it is no longer needed.

DNF/RPM stack with CoW support

We have rebased the Copy-on-Write packaging stack in the experimental repository to match the latest updates that landed in CentOS Steam 8 proper.


We now ship a patched version of PackageKit that fixes an issue in which PackageKit could not properly load CentOS repositories because CentOS uses non-standard DNF variables for repository URLs. This issue was reported over a year ago with a fix included, but since resolution had not occurred and we needed it for the Hyperscale spin, we have shipped the fix while we wait for the maintainer to resolve the issue.


We have updated kpatch to 0.9.4, which allowed us to drop a number of patches that now carried upstream. Among other things, this new release includes support for CONFIG_PRINTK_INDEX.


We’re currently using the 5.12 kernel based on our kernel-ark artifacts. Our plan is to rebase onto the same 5.14 version that is currently in CentOS Stream 9 and tracking that going forward.


We intend on supporting aarch64 as an architecture for the SIG. Right now just under half the packages are rebuilt. Our kernel is in progress but notably missing from the aarch64 builds.

Live media

We released a refreshed set of GNOME and KDE Plasma Workstation media on October 1, which includes all the work that happened in the Hyperscale SIG since the last release at the end of July. Information and links to the media are available on the SIG website.

Health and Activity

The SIG continues to maintain a healthy development pace.


The SIG holds regular bi-weekly meetings on Wednesdays at 16:00 UTC. Meetings are logged and the minutes for past meetings are available.

The SIG uses the #centos-hyperscale IRC channel for ad-hoc communication and work coordination, and the centos-devel mailing list for async discussions and announcements. The SIG also holds open monthly video conference sessions to promote collaboration and social interaction.

Conference talks

We’ll be presenting an update on SIG activites at CentOS Dojo, October 2021.

Planned work

The SIG tracks pending work as issues on our Pagure repository. Notable projects currently in flight include:

  • using CBS to build our spin images
  • shipping an updated QEMU package in EPEL
  • integrate btrfs transactional updates as an optional feature
  • setup a continuous build pipeline for the container image on the CentOS CI infrastructure
  • build a set of Hyperscale-enabled Cloud images

Dear CentOS community,

It’s been another interesting and productive month in the CentOS project.

If you’d like to contribute your own stories or articles to this newsletter, please join us on the centos-promo mailing list.

Project News

Public Board of Directors Meetings

As part of our onging effort to increase transparency and participation at CentOS, the August board of directors meeting was completely public. You can watch the proceedings on YouTube, and see the [meeting minutes on the CentOS blog.(

We know that board meetings aren’t exactly exciting, and we’re not expecting to have a lot of people watch the whole thing, but transparancy is at the heart of Open Source, and so we are working towards opening every part of the process which has not been thus far.

After the board meeting, we held an open town hall on IRC, where various community members brought their questions and comments. The transcript of this meeting is available in the archive.

Both of these features (i.e., the public meeting, and the post-meeting IRC town hall) are intended to continue for future board meetings.

If you’re interested in attending the September board meetings, please see the centos-devel mailing list, where the invitation for September board meetings has been sent. If there’s something you would like to have discussed by the board, that thread is also the right venue for that.

CPE to staff EPEL work

We are pleased to announce that Red Hat is establishing a small team directly responsible for participating in EPEL activities. Their job isn’t to displace the EPEL community, but rather to support it full-time. We expect many beneficial effects, among those better EPEL readiness for a RHEL major release. The EPEL team will be part of the wider Community Platform Engineering group, or CPE for short.

As a reminder, CPE is the Red Hat team combining IT and release engineering from Fedora and CentOS.

Right now we are staffing up the team and expect to see us begin this work from October 2021. Keep an eye on the EPEL mailing list and the associated tracker as we begin this exciting journey with the EPEL community.

CentOS Stream 9

Also on worth reading centos-devel this month is a thread in which Brian sketched out an estimated timeline for CentOS Stream 9 progress.

In the Press

A few weeks ago Steven Dickens wrote this article about the project’s ongoing efforts to improve transparency, and include the community more in decision making.


We have a number of events coming up in the next couple of months, including our first in-person events since early 2020.

CentOS Dojo, October 7, 8

The Call for Presentations for the online CentOS Dojo in October has just closed, and we expect to post the schedule later today. This event will include SIG reports, a Board of Directors AMA (Ask Me Anything) and other technical content. We look forward to seeing as many of you as possible at that event.

During the second day of the event, we will be hosting a Bug Smash event, where you can learn how to contribute changes to CentOS Stream. This will include tooling setup, and discusison of what kinds of changes are likely to be accepted.

Open Source Summit, Seattle, September 27-30

Our first return to an in-person event will be Open Source Summit in Seattle, which will be held September 27-30th. CentOS will be in the Red Hat booth at that event, and we hope to see you there!

All Things Open, Raleigh, October 17-19

We also expect to be present at All Things Open, which will be held October 17-19 in Raleigh, North Carolina

SIG Reports

Special Interest Groups are where you can get involved providing additional packages, or other extra value, on top of the base CentOS platform. The following SIGs are reporting this month:

Artwork SIG


The CentOS Artwork SIG exists to produce the CentOS Project visual


Membership Update

We are always looking for new members.


The Artwork SIG is wrapping up the ticket about CentOS Project Logo
redesign. Final slides have been designed and will be presented to
CentOS Board next month.

The Artwork SIG releases one brand new artistic motif with each major
release of CentOS distribution. For CentOS Stream 9 distribution, the
next major release of CentOS Project, we have designed the following
artistic motif:

The Artwork SIG, in coordination with CentOS-Infra, is redesigning the
CentOS Websites and have put online the following resources so you can
test it:

The artistic motif, the websites design, and everything the Artwork SIG
does is open for contributions. If you want to participate, please send
an email to showing your interests.

Health and Activity

The Artwork SIG is not as healthy as other SIGs could be. The lack of
SIG members in it during an extended period of time is a red light
difficult to avoid. To workaround this, artwork propositions are
eventually shared in social media looking for public opinion and so get
more context for the results we produce. We need more folks to push
harder on Artwork SIG purpose.

The Artwork SIG is in doubt about the boundaries related to CentOS
branding and would like to have a clear answer to the following

  • What design process does Red Hat expect the CentOS community to
    follow regarding CentOS brand constant reviewing? How much freedom does
    CentOS community has to agree or disagree with changes coming from the
    brand owner as well as the other way around.

  • The CentOS brand is owned by Red Hat, but the process by which the
    image is produced/enhanced, could it be considered an open source
    project on its own, with open and clean directives to follow. So, to
    make visible what we can and cannot do when we talk about enhancing the
    CentOS brand?

Issues for the Board

The following issue will be brought to the Board of Directors in the September board meeting:

OpsTools SIG

Jun 01, 2021 - Aug 31, 2021


Provide tools and documentation, recommendation and best practices for operators of large infrastructure.

Membership update

Sadly, we did not attract new volunteers to contribute to the SIGs purposes, but at the same time, we didn’t loose any.


After initial euphoria setting up the SIG and getting to work, we can now observe a kind of settlement. Collectd was upgraded to 5.12 (in testing).
The next goal is to build both on CentOS Stream and also to look at what’s coming for CentOS 9.

Issues for the board

Nothing to report.

Virtualization SIG

Advanced Virtualization

  • CentOS Virt SIG has been updated with latest 8.4.0 advanced virtualization packages (qemu 5.2.0, libvirt 7.0)
  • CentOS Stream 8 SIG follows 8.5.0 pre-release packages, with most recent builds done last week (qemu6.0, libvirt 7.5)


We are pleased to announce that Red Hat is establishing a small team directly responsible for participating in EPEL activities. Their job isn't to displace the EPEL community, but rather to support it full-time. We expect many beneficial effects, among those better EPEL readiness for a RHEL major release. The EPEL team will be part of the wider Community Platform Engineering group, or CPE for short.

As a reminder, CPE is the Red Hat team combining IT and release engineering from Fedora and CentOS.

Right now we are staffing up the team and expect to see us begin this work from October 2021. Keep an eye on the EPEL mailing list and the associated tracker as we begin this exciting journey with the EPEL community.
