ksplice and CentOS
by Karanbir Singh 25 Sep '25

25 Sep '25

hi guys, lots of people on this list are keen on contributing to the CentOS effort - and one place where we could, as a group of people, make a massive difference is being able to deliver a ksplice upgrade model. A couple of people have started in silo's to try and get something together but I feel it might be a good time to try and see if we can do somethng as a group. Do we have people on the list who find the idea of rebootless kernel upgrades interesting ? Is there some desire to try and make that happen within the CentOS Ecosystem ? - KB

anaconda dependency calculation?
by Nicholas Byrne 04 Aug '25

04 Aug '25

Hi all, I'm trying to find a tool that calculates all dependencies for a specific package or group of packages for use with CentOS 5 (beta) with the intention of putting together a custom single CD build of CentOS 5. With CentOS 4 i used a python script that used the hdrlist module to find all dependencies which borrowed code from a number of sources. I've looked at yumdownloader and how it checks dependencies (using the --resolve option) but if i pass it the list of packages defined in say the Base and the Core yum groups which generally form an absolute minimal install i end up with about 200 packages. If i do a custom install (using beta 1 disks) and deselect everything i end up with over 300 packages. So i'm guessing anaconda calculates dependencies in a slightly different way, can anyone point me to files/code where i should be looking to find out?

[Feedback request] CentOS website theme readability
by Alain Reguera Delgado 17 Aug '24

17 Aug '24

Hi, The website theme is being updated to improve content responsiveness and readability, on both large and small screen devices. Your feedback would be very helpful to detect usability issues and consolidate a design that works well for you. Here is an example page you can use for testing: https://www.dev.centos.org/about/governance/sigs/#functional-sig-responsibi… Is the content of this page readable for you? If possible, provide feedback from both large and small screen devices. Thanks! -- Alain Reguera Delgado <alain.reguera(a)gmail.com>

forums + portal for {lang}.centos.org sites
by Karanbir Singh 17 Aug '24

17 Aug '24

Hi, Earlier in the evening today Ralph, Fabian and I had a chat about the present state of the language subsites. This email sort of summarises the main issue ( s/w ). We seem to have run into a slight technical hitch with punbb/fluxbb. They dont support LDAP as a backend. And we had decided a few months back that all new rollouts must have ldap backend so we can rollin CentOS-DS / openldap based backend. So we need to look at alternatives, and since the primary focus of these international sites is going be forums : Here is a shortlist ( if there is anything else that people are aware of, please add to this list ) - phpBB - SMF - Fudforum - phorum - fluxbb Requirements: - Must be able to scale ( couple of hundred thousand msgs ) - Must be able to handle ldap auth ( if it cant, whats involved in writing the ldap-auth portion ) - Must address the specific requirements raised by the present www.centos.org forum users ( Can you please fill this section in ? ) - Must support all languages we need ( pure utf8 support would be good ) - Secure - Skin'able Nice to have: - Capable of running multiple instances from a single deployment - responsive community :D Things we will need to do: - Decide on what s/w to use. - Give the ArtWork people enough time to get the look & feel sorted. - Migrate newbb forums from www.centos.org to $system ( hey, english is a language too :D ). - Migrate fr.centos.org into the final s/w - setup {de/es/ja/it/pt_br}.centos.org Actions: Ralph and Fabian are going to work on setting up a test ldap server, once that is online we will then start by installing into our test-vm-farm the various s/w to eval them. If anyone would like to help, please feel free to jump right in. I'll setup a wiki page for this issue, which might be a good place to track progress. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

[REPORT] Quarterly Report - CentOS Automotive SIG
by Jeffrey Osier-Mixon 18 Aug '23

18 Aug '23

January 2023 Quarterly report submitted by: Jefro Osier-Mixon, Red Hat - chair _____________________________________ Membership update This SIG does not have a formal membership process. The mailing list currently has 106 subscribers representing at least 32 organizations, though not all subscribers use corporate emails and some are participating as individuals. _____________________________________ Releases in the most recent quarter (or most recent release, if none in that quarter) The Automotive SIG produces three types of artifacts: - AutoSD, a streaming distribution of CentOS designed for in-vehicle automotive use cases. - An Automotive SIG RPM repository that allows the community to expand the content of AutoSD or experiment with some of its parts. - Sample images, built using OSBuild, which provide examples of how to assemble production images based on AutoSD, customized for some hardware, including container images, based on CoreOS/ostree technologies. AutoSD, or Automotive Stream Distribution, is a streaming distribution for automotive in-vehicle software development based on CentOS Stream. It is transparently the upstream project for Red Hat's eventual in-vehicle OS product. AutoSD has been downloaded and used by many organizations who have commented or asked for help, so we know it is getting some traction though of course we don't have exact metrics on usage. In Q4 2022, we released a version of AutoSD compatible with the emerging SOAFEE specification. SOAFEE (https://soafee.io) is an initiative driven by Arm for the purpose of developing a reference specification for Arm-based software-defined vehicles (SDVs) consisting of an operating system, container orchestration strategy, and application layer. In addition, we introduced a very lightweight container runtime based on podman and systemd that does not include Kubernetes, as the latter represented a significant performance hit on all relevant hardware. We presented at the Arm Developer Summit in November on these topics. In the coming quarter, we plan to tighten up documentation, begin a process for accepting and supporting hardware enablement contributions, and continue to develop AutoSD toward the SOAFEE specification while also contributing to that specification within the SOAFEE community. _____________________________________ Health report and general activity narrative The SIG typically has 1 public meeting per month with 25-40 attendees, with visible participation from 7-10 separate organizations. We have largely given up on a separate office hours meeting due to attendance. This SIG is intended to be a community effort with contributions and shared benefits from all participants. All formal meetings are recorded and posted on this page: https://wiki.centos.org/SpecialInterestGroup/Automotive/Meetings Several Red Hat employees made the initial contributions to the project as well as the infrastructure required to build and test it. We occupy a gitlab repository in the CentOS namespace building software regularly using CI, with build instructions provided on the documentation page at https://sigs.centos.org/automotive/ . Sample images are present and downloadable along with customization and build instructions. _____________________________________ Issues for the board to address, if any None, keep up the excellent work :) Jeffrey "Jefro" Osier-Mixon | jefro(a)redhat.com Red Hat Office of the CTO | Sr. Principal Community Architect, Automotive

Scheduling the CentOS ISA SIG meeting
by Florian Weimer 01 Jul '23

01 Jul '23

I'd like to propose bi-weekly meetings for the ISA SIG. What about reusing the slot of the Fedora ELN SIG in alternating weeks? The first meeting would then be Friday, July 7th, 16:00 UTC. I proposed that here: Schedule initial sequence of ISA SIG meetings <https://github.com/CentOS/Calendar/pull/62> I'm aware of the holidays in Czechia and the United States next week, but it's just the first meeting, with more to follow. If that slot doesn't work in general and you want to participate in the meetings, please let me know (off-list if you prefer). Thanks, Florian

Adding bootc images - part of Cloud SIG or separate?
by Colin Walters 30 Jun '23

30 Jun '23

Hello, I'm a developer on Fedora/RHEL and OpenShift. Lately we've been landing a lot of "bootable container" changes in OpenShift core, and there's a lot more to come. However, as we've been doing about this...I've been saying to people that I wish I had a time machine to go back and do bootable containers from the start. There's a lot of things we're doing today that I think we should stop doing, e.g.: - Switching to kernel-rt by fiddling with each node; we should be simply pulling a pre-built bootable container image with that kernel (more on this below) - Getting away from injecting so much persistent state by default (both via Ignition and outside of it) And crucially, I think we should be developing tools and techniques that apply *outside* of Kubernetes/OpenShift and also work well with it. To be direct, I'd like to eventually productize some of what's happening here in RHEL, not in OpenShift. As part of this (potential) re-architecture of how we think of systems management, I created the https://github.com/containers/bootc project. To be direct: If successful, I think bootc will be the successor to (rpm-)ostree. It's also intended to much more closely align with the github.com/containers organization. A simple way to think of this is: One can (build and) run *application* containers with podman; and these containers can also be run in e.g. Kubernetes/OpenShift. One can build *bootable* containers using any tooling (including podman build), but *running* them is via bootc on the end machine. bootc understands kernels etc. But there's a lot to figure out here - and I want to have a space to figure out this stuff and experiment with it outside of a direct-to-product path. I think a CentOS SIG makes sense for this. So what I'd like to do is either: - Add a new effort to the Cloud SIG, which currently (IMO a bit confusingly) hosts OpenStack/RDO and OpenShift/OKD things which would be a 3rd thing. The bootc work would then be the "base OS" split for OKD/SCOS. But of course, nothing stops one from building bootable host images that are instead designed to be RDO/OpenStack hosts. - Or, create a new SIG Personally, I lean towards the latter because honestly I find the naming "Cloud" to be misleading - bootc is also intended to be useful for standalone, non-cloud-infrastructure settings (such as desktops and IoT). Specifically, I'd like to transfer the existing code that lives in https://github.com/cgwalters/bootc-demo-base-images (specifically https://github.com/cgwalters/bootc-demo-base-images/blob/main/c9s.yaml ) into something CentOS-affiliated and explicitly maintained by a team. (Though I'm not super excited to move it to pagure like at least some other SIG content, but let's not get distracted by git hosting too much here). Another way to say it is that I'd love to ship quay.io/centos/centos-boot:stream9 (notice the -boot). Or failing that, it'd be quay.io/centos-boot/centos-boot:stream9 or so. There's a *lot* to discuss in terms of what actually goes in these base images, and also ensuring it's equally ergonomic for users to build their own base images. So really it's very likely there wouldn't be just *one* base image. In fact, I recently introduced a -rt variant with the RT kernel: https://github.com/cgwalters/bootc-demo-base-images/commit/68afb072a5a1396c… - and this was specifically motivated by issues we hit in OCP. But again, I want to have a space where we try to do more of a "clean(er) slate" approach for a while, with notes "not for production use" - for a while. Everything done here though *is* made with that as an explicit goal though (e.g. it's a toplevel design goal too that existing ostree-based systems can be seamlessly switched to be container-based without reprovisioning). At the same time, bootc already introduces some quite new things that need design iteration; for example: https://github.com/containers/bootc#using-bootc-install - we ship tooling such that a container can install itself (without going through a raw disk image as is used by both OCP and Edge deployments today). And at the same time, I'd like to aim to get the Anaconda changes to install these bootable containers in https://github.com/rhinstaller/anaconda/pull/4561 OK this is already too long, so I'm just going to click send =) Thoughts?

Where can I find updated CentOS artwork?
by Gordon Messmer 29 Jun '23

29 Jun '23

I don't want to reopen https://git.centos.org/centos/Artwork/issue/1 , but I'm not sure where to ask questions about the status of that work. The centos.org sites (www., wiki., and git.) use updated logos, but I can't find any updated artwork described at https://wiki.centos.org/ArtWork or any linked page. It's possible that I'm overlooking it. Any pointers?

ISA SIG rebuild status
by Florian Weimer 29 Jun '23

29 Jun '23

Last week, the ISA SIG concluded two rebuilds of a snapshot of CentOS 9 Stream with GCC 12, one with -march=x86-64-v2 (same as CentOS 9 Stream), and one with -march=x86-64-v3. The rebuilds are fairly complete. The following things are missing: * All modular content. * LibreOffice and OpenJDK. * Two Rust packages which require a rebase of their bundled rust-bindgen versions for Clang 16 compatibility. (Rust currently does not follow the subarchitecture in CFLAGS anyway.) I classifed most of the initial build failures, and here are some numbers: GCC 12 induced failures GCC 12 exposes latent undefined behavior 2 various issues (mostly -Werror) 18 GCC 12 C++ header inclusion changes 3 subtotal 23 x86-64-v3 test differences 7 general buildroot/time/policy changes 19 grand total 49 (We switch to GCC 12 for auto-vectorization at -O2 using the very-cheap cost model, something that cannot be model with GCC 11 compiler flags. Without that, a forward-looking comparison between -march=x86-64-v2 and -march=x86-64-v3 is not possible.) The x86-64-v3 test differences are mostly due to GCC's -ffp-contract=fast default, which does not match what some package test suites expect. We saw those on other architectures already, and with -march=x86-64-v3, GCC supports FMA, exposing them for the x86_64 architecture as well. Maybe upstream GCC can revisit the default there. The general failures are in some cases literally due to time because test certificates expired, or a hard-coded date in some test is no longer in the future. Disabling SHA-1 broke some tests as well. The rest is just general drift of build dependencies, introducing incompatibilities. FTBFS bugs have been filed in Red Hat Bugzilla as appropriate. We were able to eliminate a bunch of rebuild issues that are specific to the CBS Koji environment and do not show up in other environments. I should probably send out a separate note about that, in case other SIGs want to do mass rebuilds. We are still working out how to best deliver the rebuilt packages for testing. Until then, the packages are available from the Koji buildroot and can be (mostly) installed with “dnf distro-sync” from an existing CentOS 9 Stream system: <https://cbs.centos.org/kojifiles/repos/isa9s-packages-baseline-el9sbase-bui…> <https://cbs.centos.org/kojifiles/repos/isa9s-packages-optimized-el9sopt-bui…> I would like to thank Troy Dawson for shepherding the build process and reviewing and fixing issues, and Brian Stinson for resolving CBS Koji infrastructure issues.

How was the old centos git repo maintained?
by Gordon Messmer 23 Jun '23

23 Jun '23

I never paid much attention to the repos in the past, but after reading a comment about "exploded src.rpms" I picked one to review... (https://git.centos.org/rpms/bash/commits/c8) It looks like there was a process (or a person?) that would unpack released src.rpms into a git repo, delete Source0, and then commit whatever was left. Is that approximately correct?

2023-06-14 - CentOS Public Board Meeting
by Thomas Oulevey 13 Jun '23

13 Jun '23

Hi Everyone, Our next board meeting will take place at 20:00 UTC tomorrow: `date -d "2023-06-14 20:00 UTC"` If you would like to attend please send me an email to alphacc(a)centosproject.org ( please do not reply to @centos-devel or use another email address) and you will receive a link to a Zoom meeting room with a passcode, 1 hour before the meeting takes place. The agenda can be checked at (work in progress) : https://hackmd.io/@centosboard/ry93GGRI2 As a reminder we will enforce few rules : * Wait to be recognized by the Chair before speaking * Respect the Chair when told your time to speak is over - this will allow us to remain on agenda, and complete the meetings in the allotted time * In the event that there are Board-confidential topics, these will be put at the end of the meeting, in Executive Session, and guests will be asked to leave. We hope to minimize these items, but they do sometimes happen. The most common scenarios in which this may happen are personnel issues, or information that Red Hat wishes to share with the Board, but is not yet public. * Muting of participants, or, in extreme situations, ejection from the meeting, is at the sole discretion of the Chair. * Meetings will be recorded, and published to YouTube (possibly with edits/redaction, as approved by the Directors). Thus, by joining the meeting you consent to have your presence at the meeting, and anything you say during the meeting, made public. I hope some of you can join. Sorry for the late announcement. thanks, -- Thomas 'alphacc' Oulevey CentOS Board of Directors Secretary alphacc(a)centosproject.org

Planned Outage - networking upgrades - 2023-06-13 20:00 UTC
by Fabian Arrotin 13 Jun '23

13 Jun '23

Forwarding here the info that was sent to Fedora infra list ( https://pagure.io /fedora-infrastructure/issue/11365 ) In summary, today you'll probably see some services being unreachable, and impacted services are the ones located in the Fedora DC (it doesn't impact https://cbs.centos.org and others). Impacted services: - https://accounts.centos.org (and https://fasjson.fedoraproject.org that some infra services are using to retrieve users info and groups) - ns2.centos.org Worth knowing that, due to network upgrade, we'll also have to power off in advance some Virtual Machines that are located on a remote iscsi block device. And at the same time we'll also convert some VMs/KVM hosts from centos 7 to el9 Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

Discussion: Open technical questions concerning SIG content for RHEL releases
by Peter Georg 09 Jun '23

09 Jun '23

Dear all, There has been an inquiry to the CentOS Board to clarify how long SIGs can expect to be able to build against RHEL build targets [1]. This is necessary to allow SIGs themselves to communicate expected lifecycle of their content to users. The outcome of this, in summary, is that SIGs should be able to build against RHEL until it reaches EOL (end of Maintenance Phase) + 30 days (no access to ELS content). This policy follows the one used by EPEL. Note: It is (obviously) still up to every single SIG to decide if and for how long they want to support a particular RHEL (or CentOS Stream) release. This inquiry also included respectively raised some technical questions. These technical questions are not to be decided by the CentOS Board. In [2] it has been recommended to discuss these on centos-devel. So let's do that. I want to start with two open questions which I do know of. In case there are other open question concerning this matter please raise them here. First open question is where to push content produced by SIGs for RHEL8 to. To better understand the issue, let me summarize the current situation, for which we first need to define the used format for tags in CBS: <sig><el>-<project>-<version>-{candidate,testing,release} where <el> can currently be 7,8,8s,9,9s Packages tagged for -testing are pushed to: https://buildlogs.centos.org/centos/<el>/<sig>/<arch>/<project>-<version>/ Packages tagged for -released are push to: If el = 8 or 8s: debuginfo rpm packages: https://debuginfo.centos.org/centos/<el>/<sig>/<arch>/<project>-<version>/ src.rpm packages: https://vault.centos.org/centos/<el>/<sig>/Source/<project>-<version>/ Everything else: http://mirror.centos.org/centos/<el>/<sig>/<arch>/<project>-<version>/ If el = 9 or 9s: http://mirror.stream.centos.org/SIGs/<el>/<sig>/<arch>/<project>-<version>/ For src.rpm <arch> is source. Note: Although it is not relevant for the discussion, in fact on the mirrors the suffix "s" of <el> is replaced by "-stream". This currently is all fine. However it is planned that the infrastructure currently used for packages built for 8 or 8s will disappear once CentOS Stream 8 and CentOS Linux 7 are EOL (June 30th, 2024). So in case any SIG decides to produce content for RHEL 8 after that date packages can not be distributed properly anymore. Only using the -testing tag and thus https://buildlogs.centos.org is not really an option as it would probably produce too much load on these. My proposal: After CentOS Stream 8 went EOL (May 31st, 2024), which is the same date as the end of the Full support phase of RHEL 8, at least the -release tag of all RHEL 8 build targets is locked and SIGs have to opt-in in case they want to build content for RHEL 8 during its Maintenance Support phase (End: May 31st 2029) for a particular build target. For these, tagging for -release will then push content to http://mirror.stream.centos.org/SIGs/8/<sig>/<arch>/<project>-<version>/, i.e. the same location as used for 9 and 9s. This gives SIGs one month for all required changes before the currently infrastructure disappears. Of course this means additional work for SIGs and Infra. However at some point the location where to push content to has to be changed before the currently used infrastructure disappears. Choosing an earlier date would result in work for SIGs who do not want to continue providing any packages once RHEL 8 enters Maintenance Support phase anyway. The second open question concerns the centos-release-* packages provided by SIGs to allow users to easily consume SIGs' content. For 8s and 9s the CBS tags extras<el>-extras-common-{candidate,testing,release} are used to build these packages. This repository is added in CentOS Stream 8 and 9. For packages build for RHEL 8 and 9 there is currently no common way to provide any means of easing the process to consume SIGs' content. My proposal to fix this is by adding extras<el>-extras-common-{candidate,testing,release} for <el> = 8 and 9, i.e., using the same system as currently used for 8s and 9s. To further ease the process I propose to introduce a package named centos-release-extras which contains the repository config pointing to the content of the tags extras<el>-extras-common-{testing,release} (only -release enabled by default) and the CentOS-SIG-Extras GPG key. The centos-release-extras packages itself would be built in the extras<el>-extras-common-el<el> build target. Users of RHEL would then only need to install this single package to allow them to easily install any other centos-release-* packages. Obviously someone needs to maintain the centos-release-extras package. I volunteer to maintain this package.

Introducing the CentOS ISA SIG
by Josh Boyer 09 Jun '23

09 Jun '23

Hi All, As Florian Weimer originally proposed, we have created the CentOS ISA SIG to focus on potential benefits of newer ISA baselines and optimizations. You can find our bare-bones SIG docs here: https://sigs.centos.org/isa/ We'll be adding more information to that site over the coming weeks. For now, we're getting SIG projects setup and bootstrapped. There is a #centos-isa libera.chat IRC channel for the SIG and anyone interested is welcome to join and follow along. We'd like to thank the CentOS community and Board for their support, the CentOS Infra team for the rapid response and help, and the Hyperscaler SIG for providing some great examples to follow on SIG setup. josh

Few questions on cloud images
by Pino Toscano 07 Jun '23

07 Jun '23

Hello, I have few questions related to the cloud images provides for c8s and c9s, i.e.: - https://cloud.centos.org/centos/8-stream/x86_64/images/ - https://cloud.centos.org/centos/9-stream/x86_64/images/ 1) I see the c9s images are regularly updated, while the c8s images not; is this wanted, or simply a mistake/miss somewhere? If so, will they be kept up-to-date just like the c9s images? 2) are the Vagrant images there officially supported? Let's say you use one, and find a bug; then check on a "classic" installation (baremetal/VM), and the bug isn't there; can users report problems in those cases? 3) would it be possible to have either unversioned or "-latest" symlinks for the latest versions of all the files (i.e. images, checksums, etc)? This way, it will be much easier for users to fetch the latest versions with no need to change URLs frequently. Of course, the assumption is that users of this are always willing to use the latest version. Thanks! -- Pino Toscano

Migrating from CentOS Stream 8 to 9
by Troy Dawson 06 Jun '23

06 Jun '23

I've started getting questions about moving from CentOS Stream 8 to CentOS Stream 9. I am not the biggest expert on that, so I am bringing the question to the community. Have you migrated a Stream 8 machine to Stream 9? If so, would you mind sharing your steps? I've already had one person respond as I asked around, and this is the writeup that they used, with some minor changes (different packages). https://ahelpme.com/linux/centos-stream-9/how-to-upgrade-to-centos-stream-9… Troy
