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

Build scripts for CentOS 7 AMIs
by Brian Lalor 04 Aug '15

04 Aug '15

I’ve been unable to find the build scripts used to create the CentOS 7 AMIs. I have found them for docker, vagrant, and I believe openstack. Can those please be published? — Brian Lalor blalor(a)bravo5.org

Testing CentOS as a hypervisor in different scenarios
by Karanbir Singh 04 Aug '15

04 Aug '15

Hi, this has come up in a few conversations, and its worth looking into. Various efforts including the CentOS Cloud Instance SIG, would like to test their VM instances under a CentOS 6/7 hypervisor setup. I am sure the Virt SIG guys would like to also have these VM instances tested on hypervisors and environments they curate. Whats the best way to move forward on this ? I am going to propose asking the various efforts ( eg. cloud sig, virt sig ) to help setup the environments like openstack, centos-kvm, centos-xen, ovirt etc; and provide a single mechanism that can be used via jenkins at ci.centos.org to grab, test, report on machine instance states. The cycle would need to run via triggers at ci.centos.org, and it would ideally be run for the entire set of environments we can bring up. thoughts ? -- Karanbir Singh, Project Lead, The CentOS Project +44-207-0999389 | http://www.centos.org/ | twitter.com/CentOS GnuPG Key : http://www.karan.org/publickey.asc

Adding midonet-release to CentOS Extras (as a CATPR?)
by Sandro Mathys 30 Jul '15

30 Jul '15

Dear all, We, the MidoNet community [0], would like to include a midonet-release (or similarly named) package with the required yum repo files into CentOS Extras - similar to epel-release or centos-openstack-release packages in the same repo. For reference, our repos live at [1]. MidoNet is a network virtualization software and while our main focus is currently OpenStack, other use cases exist and will get more attention in future (mostly containers I guess) - which is why we would like to be included in CentOS Extras and not just in centos-openstack/rdo repos (if these accept release packages at all). I asked in #centos about this and was pointed here, so I hope someone can tell me what the process for this would look like and how to get started with it. I was told that IUS is undergoing the same process but couldn't find any information about this. I was also pointed to the "CATPR" guidelines [2] which I found to likely still being in draft status [3] but it should be no problem to fulfill the given requirements. We're only providing add-on packages and we have a bug tracker to report issues [4]. Cheers, Sandro Mathys MidoNet Community Manager [0] https://www.midonet.org/ [1] http://repo.midonet.org/ [2] https://gist.github.com/carlgeorge/ae71d54c99d3536ee352 [3] http://wiki.centos.org/CarlGeorge/CATPR [4] https://midonet.atlassian.net/secure/Dashboard.jspa

Update where we are with SCLo SIG
by Honza Horak 29 Jul '15

29 Jul '15

A small update for anybody who didn't follow the discussions last weeks around Software Collections in CentOS. Since we got quite a lot requests for devtoolset-3, we started with this collection. That one also requires the most problematic collections maven30 and rh-java-common, that are quite challenging to be rebuilt. Some packages that do not require java packages are already built in cbs.centos.org and available in this repo: http://cbs.centos.org/repos/sclo7-devtoolset-3-sclo-release/x86_64/os/ In order to accomplish the successful rebuilding of all packages we decided to import binary packages into cbs.centos.org as an external repo and rebuild the collections using those packages. Great news from today is it seems the imported packages work -- I was able to build the package devtoolset-3-apache-commons-el that during build needed a package not build in CBS yet (devtoolset-3-hamcrest, successfully used from the imported set). Completing my action items from last meeting: Task bug for creating tags for maven30 and rh-java-common collections: https://bugs.centos.org/view.php?id=9150 Task bug for creating components in dist-git for collections maven30, rh-java-common and devtoolset-3: https://bugs.centos.org/view.php?id=9151 The next step now is to rebuild those three collections using the external repo, while storing the sources into git.centos.org already. Branches for those packages will follow patterns described at http://wiki.centos.org/BrianStinson/GitBranchesandKojiTags, which means e.g. packages for devtoolset-3 will use branch sig-sclo7-devtoolset-3-sclo. Look-aside cache is still not ready, but Fedora's look-aside cache should be fine enough in most cases. Honza

CR repo update problem
by Fred Smith 29 Jul '15

29 Jul '15

FYI, I ran all the (then current) updates from the CR repo this morning, and found that it stepped on my sendmail.cf. (presumably the sendmail rpm was the culprit.) I wouldn't think that was the desired beavhior, would you? I'd expect it to drop either a rpm.old or rpm.new file instead. luckily, easy to fix once I figured out why incoming mail was busticated. -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. ------------------------------- Romans 5:8 (niv) ------------------------------
