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

cbs feature req: building embargoed content
by Karanbir Singh 12 Mar '15

12 Mar '15

hi guys, we need a way to build embargo'd content like reimzul's priv-build, that does not make stuff public till a specific date ( the actual push to public can be manual ); how would we achieve this on cbs ? I guess the git stuff is easier since it can just be a scratch build from srpm and people need not push the git content back to git.centos.org till embargo expiry. - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

CentOS Bug Tracker and ABRT
by Jakub Filak 04 Feb '15

04 Feb '15

Hello everyone, I want to briefly introduce myself. I am a Red Hat employee working on ABRT[1]. We have recently added support for CentOS on the ABRT server[2] and we would like continue in these integration efforts. First of all, I want to submit a pair of patches improving ABRT's UX on CentOS: - do not offer users to report to Red Hat Portal - offer users to send an email to upstream - stop wasting of resources by running sos, because its output is useless for CentOS users In the near future, we would like to integrate ABRT with CentOS Bug Tracker in the same way as ABRT integrates with Red Hat Bugzilla[3]. We are done with the analysis phase[4] and, now, we are working on a testsuite[5]. Unfortunately, MantisBT misses more advanced searching what prevents us from implementing a tool similar to one we have for Bugzilla. At least we need to search by DUPHASH (an unique identifier of a crash, something like tag). Would you be willing to run a MantisBT plugin adding the things we need, if we develop it?

Port CloudSigma to CentOS's CloudInit
by Viktor Petersson 29 Jan '15

29 Jan '15

Hey guys, I had a conversation with Jim Perrin and Karanbir Singh about this and it should be relatively trivial. However, Jim suggested that we moved the discussion here. Here is the status today: * The CloudSigma provider for CloudInit is complete and is maintained by Canonical[1] and is included in (12.04 and forward) * Jim wrote a patch (attached). It isn't complete, but it is a start. * There is also a port to CoreOS (re-written in Go) [2] * Since I didn't write the code, I don't know of the exact workflow, but I think these are the relevant files: ** cloudinit/cs_utils.py ** cloudinit/sources/DataSourceCloudSigma.py ** tests/unittests/test_datasource/test_cloudsigma.py I'm involved with CloudSigma, and I'd be happy to sponsor anyone willing to take on the task of porting this with resources at CloudSigma for testing. Unfortunately, I don't have any internal resources to allocate towards this at this point, but I know that we have plenty of customers running CentOS that would love to see this happen. I'd also be happy with answering any questions and help with the QA of this. Thanks!

CentOS Atomic host repo now has nightly updates
by Karanbir Singh 16 Jan '15

16 Jan '15

hi, the CentOS Atomic Host repo is now getting nightly updates. These are done automatically, and pushed to the repo location on buildlogs.centos.org/centos/7/atomic/x86_64/repo In order to apply the updates, login to your atomic host and run : sudo rpm-ostree upgrade You can also see the Atomic history and rollback options via: sudo atomic status In order to compare available rollback options, you can use the 'atomic rpm diff' and 'atomic rpm list' commands. Finally, you can rollback the changes using this atomic command; details on the process are mentioned in the man page available via 'man atomic' on the machine instance. ------- The repo is updated with all devel components going into the Atomic host, including docker, cockpit, flannel, kubernetes and rpm-ostree itself. Additionally, all CentOS Linux 7 updates are included as well. Highlights from todays update include: cockpit 0.27 docker 1.4 kubernetes 0.7.0 ostree 2014.13 kernel 3.10.0-123.13.2.el7 and added to the collect is : flannel 0.1.0 -------- Getting Started with CentOS Atomic Host is easy, the image is shipped as a qcow2.xz file ( 270MB in size ) and can be downloaded from http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-AtomicHos… this image includes cloud-init, and therefore expects cloud metadata to be available when the instance is booted up. You can find details on howto setup an iso file with this informat at : http://www.projectatomic.io/blog/2014/10/getting-started-with-cloud-init/ Enjoy! -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Image building features enabled in CBS
by Ian McLeod 14 Jan '15

14 Jan '15

Hello all, Thanks to Thomas' (alphacc) work last Friday, we now have the image building features enable on the CBS koji instance. I'll give a very brief summary of how to use it. The general form of the koji command is: koji -p cbs image-build <image_name> <image_version> <build_target> <install_tree_url> <arch> --release <image_release> --distro <distro_name_version> --kickstart <local_kickstart_file> --format <format_type> --disk-size <disk_size_in_gb> --repo <repo_url> (optional) --scratch (optional) --nowait (optional) The image build must be given a name, version and release. These function in much the same way as they do in RPM. In particular, the name must be added as an allowed package in the output tag for the <build_target> provided on the command line. You can specify more than one --format option. The most useful options are: 'raw-xz' - xz compressed raw file 'qcow2' - qcow2 'rhevm-ova' - A single file OVF image (aka OVA) for RHEV-M 'vsphere-ova' - An OVA for vSphere/VMWare 'docker' - A docker base image, suitable for "docker load" Any "url" or "repo" lines in your input kickstart file will be removed. The "url" line is replaced by whatever <install_tree_url> you give above. You can, optionally, provide additional repos to Anaconda by giving one or more "--repo <url>" arguments. Until we sort out how exactly we want kickstart files store in RCM (likely git.centos.org) we will be restricted to doing scratch builds, indicated with a "--scratch" option above. Here is the exact command I used to do initial testing of the feature: koji image-build \ centos-7-imcleod-test 1 atomic7-el7.centos \ http://mirror.centos.org/centos/7/os/x86_64/ x86_64 \ --release=1 \ --distro RHEL-7.0 \ --kickstart=/tmp/RHEL7.auto \ --format=qcow2 \ --scratch \ --nowait \ --disk-size=10 The "RHEL7.auto" kickstart is the minimal/JEOS RHEL7 kickstart from Oz, available here: https://raw.githubusercontent.com/clalancette/oz/master/oz/auto/RHEL7.auto In order for this to work I had to ask alphacc to add me to the "image" permission in the CBS. I then had to add the centos-7-imcleod-test "package" to the "atomic7-testing" tag (which is the destination for the "atomic7-el7.centos" build target). The command to do this was: koji add-pkg --owner=imcleod atomic7-testing centos-7-imcleod-test Please follow up with questions, thoughts, RFEs, etc. -Ian
