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?

forums + portal for {lang}.centos.org sites
by Karanbir Singh 16 Aug '24

16 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

CentOS 8 Artwork needed
by Rich Bowen 31 Jan '20

31 Jan '20

To all the artists and designers here, we need your help. With RHEL 8 beta released, we need to start producing artwork for CentOS 8. It's time for the CentOS Artwork SIG, and anyone else that's interested in contributing to this effort, to start working on everything that will be needed for the new release. What we know we need is anaconda artwork, and new desktop backgrounds to replace the current '7' themed stuff. As we dig, we may find more things that need to be updated to the new 8 theme. Additionally, we will need to update some of the assets listed here: https://wiki.centos.org/ArtWork/Identity ... and produce new assets for 8 to be listed here: https://wiki.centos.org/ArtWork/Brand/Logo And, finally, we need someone to step up to lead this effort. While we don't yet know for certain when RHEL 8 will officially release, it's safe to assume that it's soon, and we need your help. -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

Reasoning behind RHEL8 packages without corresponding -devel?
by Anthony Alba 12 Dec '19

12 Dec '19

(Of course, we should be asking RH... but nevertheless) EPEL 8 has several issues regarding packages without corresponding -devel. E.g., libXvMC, libbluray. I see that this causes grief for EPEL 8 and collateral damage to RPMFusion. Did RH disclose the reason for this? Was there any discussion on where CentOS will put them, like in Extras perhaps? (I was rolling out some testing VMs in RHEL8 and OL8, and noticed the new but "unsupported" CodeReady repos with -devel packages; yet not all -devels are them.) Cheers Anthony

Using mirrorlist in centos-release-* packages
by Anssi Johansson 12 Sep '19

12 Sep '19

Hi, as mentioned in https://lists.centos.org/pipermail/centos-devel/2018-September/016949.html mirrorlist.centos.org has been updated to produce mirror lists for SIG content as well. Some centos-release-* packages have already been modified to use mirrorlist.centos.org instead of mirror.centos.org, but many still point to mirror.centos.org. Most of mirror.centos.org hosts are also used for seeding the 600+ external mirrors we have. By directing some of their download traffic to external mirrors we can offer faster sync speeds for those external mirrors, and for people downloading individual rpms from mirror.centos.org. Second, most of those external mirrors offer faster download speeds to end users than what could be achieved by downloading from mirror.centos.org, so the users will benefit from this change as well. The better geographical coverage does not hurt either. mirror.centos.org nodes are donated servers, and it would be kind to the sponsors to use their bandwidth sparingly. The .repo files should be modified so that the current baseurl line gets commented out and a mirrorlist entry gets added, like this: mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch… #baseurl=http://mirror.centos.org/$contentdir/$releasever/storage/$basearch/gluster-4.1/ Note that mirrorlist.c.o can automatically choose between main and altarch content based on the arch parameter. The repo names are constructed from the repository path by stripping away the architecture and changing any slashes to dashes: sclo/x86_64/rh -> sclo-rh, sclo/x86_64/sclo -> sclo-sclo, paas/x86_64/openshift-origin311 -> paas-openshift-origin311, storage/x86_64/gluster-5 -> storage-gluster-5 etc. You can use 'curl' to check what mirrorlist outputs for your repository. New repos are added to mirrorlist.centos.org automatically once the repository hits mirror.centos.org. That script is currently run every three hours. I guess it could be run more frequently (it's fairly lightweight), but you should give the external mirrors a few hours to sync before announcing your release anyway. You can either submit an update to your current centos-release-* file now, or wait until you need to create a new centos-release-* package for other reasons such as releasing softwarepackage-(version+1) which uses different paths. My recommendation would be to submit an update to your current centos-release-* package, so that you would not need to worry about this when you eventually need to publish a new one for other reasons. We released an updated centos-release package for CentOS AltArch before 7.6.1810 was released for this exact reason, ie. we didn't need to worry about this change at 7.6.1810 release time. Other people (such as bstinson, arrfab and hughesjr) can probably help with creating and publishing an updated centos-release-* package, but the usual tagging procedure to extras will apply. The SIG Guide https://wiki.centos.org/SIGGuide should have all the needed details for this (if not, complain to bstinson). It is highly recommended to actually test your new centos-release-* package from buildlogs before you ask that package to be signed and pushed to extras. The holiday season is fast approaching so (I) don't expect much activity regarding these changes in the following days. I'm hoping that the SIGs would take a look at this in early 2019, though. Thanks to those SIGs who have already made these changes to their centos-release-* packages! If you have questions, feel free to ask either here or on #centos-devel. Thanks for your time!

SIG Content to remove for the 7.7.1908 release
by Johnny Hughes 11 Sep '19

11 Sep '19

For all the c7 SIGs, if you have content that you want removed (to make inactive) when we create the new 7.7.1908 tree, please let me know here what needs to be removed. If all files in a specific directory can be removed, you can just list the directory. You will also obviously need to make any changes to your centos-release-* files to remove those file locations from your repos. After we release 7.7.1908 .. we will copy over the SIG directories prune the SIG content. The http://mirror.centos.org/centos/7/<repo>/ paths will then be shifted to the new 7.7.1908 tree. I expect that some time early next week we will release the CR content .. with the full release coming 7 to 14 days after that .. so full release likely some time between 29 August to 6 September 2019. If you don't tell us to remove content, we will move everything over as is. Thanks, Johnny Hughes

CentOS oVirt Guest Image test report
by Sandro Bonazzola 23 Aug '19

23 Aug '19

Hi, tested https://buildlogs.centos.org/centos/images/ovirt/CentOS-7-x86_64-oVirt-2019… and seems overall functional. The ovirt-guest-agent service is disabled. Pushed https://github.com/CentOS/sig-cloud-instance-build/pull/157 for fixing it, please review / merge. I think we can limit the release to the qcow2c image only.
