ANN: Hyperscale (GNOME/KDE) Workstation snapshot 20210724 LiveDVDs
by Neal Gompa 24 Jul '21

24 Jul '21

Hello all, As I announced a month ago[1], the CentOS Hyperscale SIG started producing an experimental Hyperscale Workstation Spin to showcase the technologies we're working on to the broader community. Today, I'm pleased to announce we've made updated images again! Notably, this refresh not only includes an updated experimental GNOME Workstation ISO, but now we have an experimental KDE Workstation ISO, based on the great work that Troy Dawson has done to refresh KDE Plasma in EPEL[2]. The spins are available here: * GNOME ISO: https://d2r1r30d0ahkv5.cloudfront.net/CS8-HS-GNOME-LIVE-20210724.iso * KDE ISO: https://d2r1r30d0ahkv5.cloudfront.net/CS8-HS-KDE-LIVE-20210724.iso * SHA512 checksums: https://d2r1r30d0ahkv5.cloudfront.net/CS8-HS-LIVE-20210724-CHECKSUMS (Apologies for the ugly domain, we've filed a request to fix this with CentOS infra: https://pagure.io/centos-infra/issue/389) The changes with this build from last week's[3] (aside from updated packages and new KDE flavor): * SELinux denials with systemd-hostnamed and systemd-oomd should no longer occur. The SELinux policy module for systemd has been refreshed to resolve this. * SELinux denials with sssd and useradd should no longer occur. The other known issues from earlier announcements[1][3] are still present in this release. However, for KDE Plasma, there are several known issues: * The branding is incoherent. SDDM uses the Fedora 31 background in its theme and Plasma itself reverts to upstream branding instead of CentOS-specific branding. This is being investigated and will be resolved in a future release. * Konsole opens up as a tiny window until you resize it. This is an upstream bug: https://bugs.kde.org/show_bug.cgi?id=437791 * The application panel opens up in the center instead of on the left, and sometimes gets its own application icon when opened up. This is being investigated and will be resolved in a future release. If you find any other issues, we would definitely love to hear about them! We have a dedicated issue tracker for Hyperscale spins where we would appreciate bugs to be reported: https://pagure.io/centos-sig-hyperscale/spin-bugs We hope you enjoy it as much as I enjoyed making this!

C8 EOL DRAFT announcement
by Rich Bowen 19 Jul '21

19 Jul '21

Hi, folks, following up from the discussion over the last two weeks about the CentOS 8 EOL announcement, and specific details of that plan, I wanted to share with you this DRAFT announcement, for commentary. It's worth noting that certain aspects of this draft are not negotiable. Specifically: * We will not ship further updates after the EOL date * We will not automatically migrate CentOS Linux 8 users to CentOS Stream 8 However, other suggestions, clarifications, and edits are welcome, with the goal of removing any ambiguity or misunderstanding that might occur from a poorly worded message. ------- DRAFT BEGINS: CentOS 8 EOL messaging CentOS Linux 8 will reach End Of Life (EOL) on December 31st, 2021. Here’s what that means. In line with the EOL of previous releases, we will NOT be automatically migrating anyone to the next version (which is CentOS Stream 8 in this case). We will be shipping a rebuild of Red Hat Enterprise Linux (RHEL) 8.5 once it is released, even if that means that this is released slightly after the EOL date. The release of a RHEL point release is often accompanied, immediately afterwards, by a set of zero-day updates. We will be providing this content as part of the final CentOS Linux 8 release. There will, however, be no more updates to the CentOS Linux 8 content after that time. Additionally, with this deadline falling during a time when many of our team, as well as many of our users, will be out of the office, we intend to bend the usual EOL process by keeping this content available until January 31st. At that time, or in the event of a serious security bug in this time window (Defined as anything with a VCSS v3 score of 9 or greater), this content will be removed from our mirrors, and moved to vault.centos.org where it will be archived permanently, since we will not be able to provide updates to the content after the EOL date. DRAFT ENDS ----------------- We are considering shipping a dnf plugin that gives informational messages about the CL8 EOL, and explain the process for moving to CS8, for users who are not yet aware of the change. There is some concern around this plan due to anecdotal evidence that some people automate the capture and parsing of dnf output, and this might break that. Comments welcome on this topic, but of course if you’re reading this, you’re already aware of the EOL, making this a challenging issue to get feedback on. We welcome your comments on this proposal, and intend to publish this more widely after a reasonable comment period. Thanks!

ANN: Hyperscale (GNOME) Workstation snapshot 20210718 LiveDVD
by Neal Gompa 18 Jul '21

18 Jul '21

Hello all, As I announced a few weeks back[1], the CentOS Hyperscale SIG started producing an experimental Hyperscale Workstation Spin to showcase the technologies we're working on to the broader community. Today, I'm pleased to announce that we've made an updated image to address some issues present in the first release. Like before, the spin is currently available here: * ISO: https://ngompa.fedorapeople.org/centos/hyperscale/CS8-HS-WORK-LIVE-LATESTDE… * SHA512 checksum: https://ngompa.fedorapeople.org/centos/hyperscale/CS8-HS-WORK-LIVE-LATESTDE… The changes with this build (aside from updated packages): * The Anaconda installer icon and other branding is now correctly present and used. Thanks to Alain Reguera Delgado and Carl George for getting all this in place! * "dnf upgrade" works now, as we've refreshed our custom version of the RPM+DNF stack. * UDisks2 now has its Btrfs module installed out of the box. GNOME Disks, Cockpit, and others that use UDisks2 will now be able to properly detect and work with Btrfs (insomuch as the feature have been implemented in those tools). The other known issues from the initial announcement[1] are still present in this release. However, there is a new known issue: * Blivet is broken with MD devices with names that look like BIOS drive numbers, causing Anaconda to crash in the process. This is caused by the blivet rebase from 3.2.x to 3.4.0 without backporting the fix for this issue and is present in the CentOS Stream 8 software. Red Hat Bugzilla bug report (with patch): https://bugzilla.redhat.com/1983309 If you find any other issues, we would definitely love to hear about them! We have a dedicated issue tracker for Hyperscale spins where we would appreciate bugs to be reported: https://pagure.io/centos-sig-hyperscale/spin-bugs We hope you enjoy it as much as I enjoyed making this! Thanks and best regards, Neal (on behalf of the CentOS Hyperscale SIG) [1]: https://lists.centos.org/pipermail/centos-devel/2021-June/077079.html -- 真実はいつも一つ！/ Always, there's only one truth!

Documenting the CentOS Linux 8 EOL process
by Rich Bowen 16 Jul '21

16 Jul '21

As we get closer to the CentOS Linux 8 EOL, we're getting more and more questions about how the EOL is actually going to work. While there tends to be a great deal of "everybody just knows how it works" among the people actually on this list, we're getting attention from a much larger audience now, and they don't know. To that end, I want to make sure we have clear documentation, prominently displayed, that sets expectations as we get closer to that December 31 date, So ... as I understand, our process is basically: 1. Copy old data to vault.centos.org 2. Update web pages and links to say it is now on vault.centos.org 3. Turn off mirrorlist to that release name (aka all requests to CentOS-8 will 404) 4. Remove the data from the main mirrors with a file saying look at vault.centos.org 5. Mirrors pick all that up in 4-8 hours. Is there more to it than this? Will we do anything different this time because CL8 is a special case? Am I missing any steps, or have I misunderstood any of the steps? Is this already documented somewhere that I simply haven't found yet? Are there any changes to this process that we *want* to advocate for, given the special nature of this particular EOL? (No, I absolutely cannot promise anything, but I can ask.)

Dependent on PowerTools
by Mike Rochefort 16 Jul '21

16 Jul '21

Based on the office hour earlier this week, I spent some time performing scans of the PowerTools repo to see what packages from BaseOS, AppStream, and EPEL rely on it. The results of these scans can be found in a repo here: https://gitlab.com/omenos/crb-depends I was only able to do x86 based scans, and there will be some dupes of packages because i686 and x86_64 versions exist. Unfortunately this is a pretty basic check; I didn't differentiate between package types during cleanup, so there will be a lot of -devel packages showing up. Hopefully the data is accurate, I did this fairly late at night :) -- Mike Rochefort

Proper CentOS Stream value for ID_LIKE
by Mike Rochefort 15 Jul '21

15 Jul '21

When it comes to CentOS Stream, should the ID_LIKE parameter be changed to properly designate the upstream nature of CentOS in regards to RHEL? As of now, both Stream 8 and 9 are using the classic CentOS identifier of "rhel fedora". If the change of being upstream is strict enough, CentOS should be changed to "fedora", and RHEL should be altered to "centos fedora". However, I've got a feeling a lot of scripts and tooling may be looking to see if "rhel" is in the ID_LIKE parameter, which may end up preventing installations of software on Stream for limited reasons. I don't have any examples or numbers to back that up, just a hunch on how people use the os-release (and redhat/centos-release) file. Is this something that should be adjusted, or left as is for compatibility? -- Mike Rochefort
