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

A project calendar
by Karanbir Singh 11 Dec '14

11 Dec '14

Hi There is quite a lot of stuff going on and not all of it is easily visible to everyone. The way to perhaps address that is to setup a project calendar that people can sync against and look at regularly. And more win if we can have it slightly open ended, allowing people / projects / sig's to contribute events into that cal. To that extent Stephen Smoogen introduced me to Pierre-Yves Chibo who runs the fedocal effort, and they have graciously agreed to set something up for CentOS as well. Stephen I know is on this list already, I've requested Pierre to join ( he might have done so already ). Firstly looking for comments on the idea / plan - and then for options on implemention, publishing and consumption of the calendar.

cloud-init in CentOS
by Sam Kottler 02 Dec '14

02 Dec '14

During the cloud instance SIG meeting today we talked about future plans for cloud-init in CentOS. Right now cloud-init is included as part of EPEL and that's where most CentOS users consume it from. The problem is that cloud-init and related bits are critical for building images to run on a public or private cloud, and we need to build early guest initialization tools into the cloud images we produce. Ideally this does not include adding EPEL or packages from EPEL which have not been rebuilt in our build systems. So, the proposal that there's general consensus upon within the SIG is to maintain cloud-init, its dependencies, and any related packages on git.centos.org and rebuild them ourselves. I'm one of the maintainers in EPEL so I offered to maintain the git repos for CentOS, anyone else who would like to be involved in more than welcome to step up. Thoughts, questions, concerns? -s

RFC: Alternative Desktop SIG
by Stephen John Smoogen 01 Aug '14

01 Aug '14

I would like to put together an alternative desktop sig which will build, qa, and support desktops which are not the Enterprise Linux primary or secondary desktops (GNOME and KDE). There are a couple of ground rules I would like to propose: 1) Any desktop system needs to have 3 sponsors who are people willing to do the work of building RPMS, coordinating user bugs with upstream, and fixing packages. The reason for 3 is a) that this SIG isn't a dumping ground for here is ABC-DE compiled, goodbye. b) that disagreements between sponsors should be deadlock free. c) that when people take vacations, etc there is continuity of operation. 2) Desktops do not keep to Enterprise lifetimes, but major version changes to the desktop need to be announced, tested and released to a schedule. Desktops which don't want to do that will not be part of the SIG. [A schedule does not need to be super detailed, but just alleviate surprise.] 3) Desktops can and will be removed from the SIG if there isn't an interest in keeping them up. This is mainly to cover that if ABC-DE desktop no longer has sponsors, other members of the SIG aren't obliged to support ABC-DE if they don't want to. 4) Some level of governance needs to be established so that there is a committee that can make sure that a desktop has 'sponsors', that it is not just code thrown over a wall and left, and that users are not left surprised when updates to the desktop occur. They may also make up packaging rules and guidelines as needed to alleviate problems that come up. As this is an RFC, these are just proposed rules to be solidified when the CentOS board considers the SIG. -- Stephen J Smoogen.

centosplus kernel naming
by Jim Perrin 25 Jun '14

25 Jun '14

As we gear up for the upcoming CentOS 7 release, we're tracking a few things for the CentOSPlus kernel as well. One of the proposals (via http://bugs.centos.org/view.php?id=6828 ) is that we change the current name of the centosplus kernel to be a bit more consistent with other kernel names. The proposed new name would look like 'kernel-plus' or 'kernel-centosplus'. This is in keeping with other kernel names such as 'kernel-ml', 'kernel-xen', 'kernel-lt' etc. And allows for /etc/sysconfig/kernel to be used to set the DEFAULTKERNEL as desired. This change would only be for CentOS 7. Thoughts, comments, questions, flames? Please speak up with support for or against this change. -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

Next Cloud Instance SIG meetup
by Karanbir Singh 02 Jun '14

02 Jun '14

hi everyone The next meetup for the Cloud Instance SIG is scheduled for 16:30 UTC on the 2nd July 2014 at #centos-devel @irc.freenode.net At this meeting, I am hoping to demo the image building process, the automation around it, the kickstart repos around it and how people can consume this service. The setup works to build docker images, HVM images and AMI's delivered via various fileformats ( tar, qcow2, vmdk, raw ); The intention is to iterate over this setup and eventually get to a point where this becomes, curated by the Cloud Instance SIG, the official CentOS image build and delivery mechanism. Everyone is welcome to come along and join. Regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Reminder: VoIP SIG Hangout today Feb 13, 16:00 UTC
by Patrick Laimbock 28 May '14

28 May '14

Hi, Reminder: as previously announced on the centos-devel list, the VoIP SIG Hangout will be today Feb 13 at 16:00 UTC [0]. For more information how to join the hangout on Google+ or follow it on Youtube please check http://wiki.centos.org/OfficeHours Nothing set in stone but some of the things open for discussion are the scope of the VoIP SIG, the goal, the target audience, the deliverables, content distribution and lets not forget the actual proposal. It's also helpful to get an industry perspective, how to make the production side easier and facilitate processes that improve the usability of CentOS in the VoIP sector.

schedule based updates
by Karanbir Singh 28 May '14

28 May '14

hi, this is following on from the last Cloud Instance SIG meeting - the idea that we should be doing image updates was proposed, but I dont believe we decided on a time frequency of these builds. We can potentially do nightly builds and push them to ci.dev.centos.org, so if people want to really get a nightly snapshot they can. However, for most production requirements it makes sense to have these builds refreshed on a pre-determined schedule. Should we then be doing these weekly ? monthly ? When there is a major security issue ? Who decides its big-enough-an-issue ? This would then include container, VMs and cloud instance images. - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Docker problems with centos 6 image based on libselinux.
by Daniel J Walsh 27 May '14

27 May '14

People are reporting problems in Fedora about using centos rhel6 images. https://bugzilla.redhat.com/show_bug.cgi?id=1098120 The problem is the libselinux in the centos image is reporting that SELinux is enabled to processes running within the container. Tools like useradd and groupadd to attempt to write to /proc/self/attr/* files in order to setup proper labeling for SELinux. Since /proc is now mounted read/only within the docker containers, the writes are denied and useradd/groupadd fail. I wrote the attached patch for RHEL6 libselinux to get RHEL6 images to work properly. Basically the patched libselinux will report to processes that SELinux is disabled if the selinux file system is not mounted or mounted read/only. The fixed version of libselinux is already in Fedora and RHEL7 versions of libselinux. Red Hat will be shipping this new version of libselinux in rhel6.6. But we will also ship it as part of our rhel6.5 Base Image. Privileged containers and systems with SELInux disabled do not have this issue, however systemd with SELinux in permissive mode or enforcing have the problem. In permissive mode the problem will continue, since it is not SELinux denying access to /proc. It is actually the fact that /proc is mounted Read/Only. Previous versions of docker did not mount the /proc file system as read/only It would be a good idea if someone could get a patched version of libselinux into the centos 6 docker image.

Small Business SIG suggestion
by Omar Eljumaily 27 May '14

27 May '14

I'm trying to see if there's interest in a small business oriented SIG. There are already small business distros based on Centos, and perhaps those groups may also want to participate in a SIG. There are certain issues related to small office servers that I believe deserve to be addressed in a community setting. For instance: 1. Easy backup, archive, & offsite mirroring. - Something that is always problematic for every small business I know regardless of server technology. 2. Security issues specifically related to small business. 3. Smooth updating. Trying to make the transition from one major release to the next as easy as possible. 4. Plugable/scalable vertical market application architecture. For instance making the platform hospitable to vertical applications like accounting systems in which the end user doesn't have to spend weeks setting up hosting stacks. 5. Easy user account management, perms setup, etc. 6. Interoperability, easy scalability with cloud systems. For instance explore ideas like having cloud based file server backup that can also be used as live system in case of local failure. Just some ideas, but anyway if anybody's interested, please let me know. Thanks, Omar

OpenNebula Variant and Cloud SIG proposals
by Jaime Melis 26 May '14

26 May '14

Apologies, I sent this to KB's direct mailbox earlier today and apparently I didn't send it to centos-devel. So I'm forwarding it now. Given that there are at least two other projects keen to make this happen, it would be great if the Cloud SIG could be a single multicloud target. -- Hello, I'm Jaime Melis from the OpenNebula project [1]. We have been involved with CentOS for the past year making a stable Cloud Management Platform [2]. I would like to hereby propose a new CentOS variant, namely the OpenNebula variant. This variant would add three roles to the CentOS installation: * OpenNebula Frontend * OpenNebula Node KVM * OpenNebula Node Xen The work for the Frontend and Node KVM roles has been completed and is ready to be released. The Node Xen role is still in progress although close to being finished. This work should take place under the Cloud SIG umbrella, which right as of now doesn't exist, so I would like to also propose the creation of this group with the aim of making the major cloud platforms work wth Centos.

The CentOS Security Response Team
by Karanbir Singh 24 May '14

24 May '14

Hi, As SIG's come up and move forward - we are going to need to have a better established, documented and process driven security response team. While we can, in a pinch, reach into and request some resources from the RedHat SRT, they are in no way bound to help or even be involved in the overall CentOS Ecosystem - and we should really setup our own group to handle these requests. In the past conversations we had thought of setting up a group of maybe 3 to 5 people, who can triage and communicate with the respective groups of people responsible for the code or infra in question. This would not only include centos resources, but also be the contact point for upstream security notices from projects associated with us. In this case, they would be the people managing security(a)centos.org - with that email address being the primary contact for projects in the SIG's upstream as well. We would also then setup a private security mailing list. thoughts ? comments ? feedback ? -- 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

Storage SIG Update
by Patrick McGarry 23 May '14

23 May '14

Hey all, Since things have been on the back burner a bit since the Inktank acquisition I wanted to refresh what's going on in the world of the Storage SIG. KB, Lala, and I met yesterday to discuss current status and as it turns out things are actually still moving along. Ultimately we have 3 major goals for the near-term: 1) Collect srpms for Ceph/Gluster to populate CentOS repo (complete) 2) Ensure Ceph/Gluster are installable from a single repo 3) Ensure Storage distro work w/ virt Ideally we would like to expand the storage considerations beyond Ceph/Gluster, so if anyone has storage tech that they would like to heap on to the pile we definitely want to make sure we're enabling as many things as possible. Perhaps the xtreemFS or mooseFS guys would care to participate? At the very least it would be good to get a non-red-hat member into the storage mix now. If anyone has questions or concerns please let me know. Once we have a workable setup I'll push that out again for some actual consumption. Thanks. Best Regards, Patrick McGarry Director, Community || Inktank http://ceph.com || http://inktank.com @scuttlemonkey || @ceph || @inktank

Creating a CentOS-only package

Is it possible to run a Centos 6.5's kernel on a Centos 5.10 installation? I have compiled a new kernel from kernel-2.6.32-431.17.1.el6.src.rpm. The kernel does not even boot on my Centos 5.10 box. Vanilla kernels from kernel.org work well. Is this about Red Hat kernel patches? Cheers, Mark
