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

Request for feedback: CentOS-Atomic container
by Karanbir Singh 25 Sep '17

25 Sep '17

hi Alpha2: registry.centos.org/kbsingh/centos-atomic:7-alpha2 The CentOS Atomic Container is a minimal ( 30MB on disk ) image that can be used to host static content, and small footprint content that does not need the entire CentOS Linux Base image. This is also not meant to replace CentOS Linux Base image as the default, we want to make it available as an additional container base for apps that find it useful. The main highlight is that it does not contain yum, but has microdnf. I am looking for feedback, and some wider testing as well as recommendations on howto further reduce size, before we move to release. You can consume this as : docker run -t -i \ registry.centos.org/kbsingh/centos-atomic:7-alpha2 \ /bin/bash regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

[Dojo] Call for presentations, CERN Dojo
by Rich Bowen 15 Aug '17

15 Aug '17

As you may know, we are planning to hold a Dojo at CERN, in Meyrin, Switzerland, on October 20th. You may find more details here: https://indico.cern.ch/event/649159/overview If you think that you may attend, and if you would like to speak regarding the work that you're doing on CentOS, your SIG, or some interesting project that you're running on top of CentOS, please consider submitting a paper: https://indico.cern.ch/event/649159/abstracts/ We've listed a submission deadline of September 14th, but we have very limited space, and will likely schedule talks as they come in, when something catches our eye. So don't wait until the last minute! We hope to see you in October! -- Rich Bowen - rbowen(a)redhat.com RDO Community Liaison http://rdoproject.org @RDOCommunity

[infra] DevCloud migration (users, please read)
by Fabian Arrotin 03 Aug '17

03 Aug '17

Hi, Some of you actually use our DevCloud (https://wiki.centos.org/DevCloud) as a playground/sandbox environment when willing to test some deployments/scratch operations. We want you to notice that we'll completely refresh that environment next week, so DevCloud itself will be unavailable during the reinstall phase, but also all VMs currently running in that environment will also be destroyed (it's a "cloud" and for dev/testing so everything could be considered ephemeral ) Details of the migration: - setting up two new dedicated storage boxes (each using SSD disks for faster storage backend for the provisioned VMs) - reinstalling the hypervisors from CentOS 6 to CentOS 7 - migrating to RDO/OpenStack (Ocata release) - DevCloud users rights in OpenStack will be synced from ACO (https://accounts.centos.org) Due to the fact that we also have to remove some physical components from some nodes to other nodes, we'll have to shutdown the whole environment. The maintenance window is scheduled for """"Tuesday August 1st, 2:00 pm UTC time"""". You can convert to local time with $(date -d '2017-08-01 14:00 UTC') We'll do our best to keep the maintenance window as short as possible, but we also have a lot of things to reconfigure behind the scene (including new network switches). We'll announce when the new DevCloud environment will be available and ready to be used. All users are so encouraged to save what they want/need before that date, as everything will disappear. Should you have questions, feel free to contact me on irc, or answer to this thread -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

Adding s390x as an alternative architecture
by Jason DeTiberus 01 Aug '17

01 Aug '17

With the current efforts under way with aarch64 and ppc64le, I would like to suggest that s390x also be added as an alternative architecture. Obviously hardware would be the biggest obstacle, but I do not see any reason why we couldn't get started with just emulated hardware. -- Jason DeTiberus
