Moving to CentOS 8 Stream
by Pete Biggs 10 Dec '20

10 Dec '20

It's got to be done, so may as well test it ... The FAQ says to do: dnf install centos-release-stream dnf distro-sync This I did and everything went fine. I checked before doing the distro- sync and there was a load of new Stream repos in /etc/yum.repos.d Rebooted the machine and dnf has gone back to only looking in 8.3, and the stream repos had disappeared. Looking in the logs I can see this: 2020-12-09T12:28:42Z DEBUG ---> Package centos-stream-release.noarch 8.4-1.el8 will be installed 2020-12-09T12:28:42Z DEBUG ---> Package centos-linux-release.noarch 8.3-1.2011.el8 will be obsoleted 2020-12-09T12:28:42Z DEBUG ---> Package centos-release-stream.x86_64 8.1-1.1911.0.7.el8 will be obsoleted and Installing: centos-stream-release noarch 8.4-1.el8 Stream-BaseOS 21 k replacing centos-linux-release.noarch 8.3-1.2011.el8 replacing centos-release-stream.x86_64 8.1-1.1911.0.7.el8 The centos-stream-release RPM does not contain any repo information, that was all in centos-release-stream that has been removed. So stream has deleted itself. It's not a good start. I also can't seem to get back to a sensible system and have now got a system with a mixture of CentOS 8 and CentOS 8 Stream RPMs with no way of installing the Stream repos from an RPM. I see that "subscription-manager" has been installed on this system now which it never was. Is CentOS also going to be part of that ecosystem as well? Fortunately this was a throw-away install. I hope no one has tried the instructions in the FAQ on an important machine! P.

Setting up NIS on Centos 8
by Mark LaPierre 10 Dec '20

10 Dec '20

Hey Y'all, I found this: https://www.server-world.info/en/note?os=CentOS_8&p=nis&f=1 I've been told in the past that NIS should not be used because of some supposed security issues. Can someone site any authoritative documentation concerning the security issues extant in NIS? My plan is to set up NIS and NFS on my home network server where I plan to host all the local home network /home directories. I'll use automount on all the other nodes to mount up the home directories when a user logs on. -- _ °v° /(_)\ ^ ^ Mark LaPierre ****

ContOS 8 is dead. Viva Rocky Linux!
by Lists 10 Dec '20

10 Dec '20

The list is swamped with news about CentOS 8 dying in a year and becoming stream Linux. IWeve been here before, folks. I remember when Red Hat Linux disappeared to become the Feodra / Red Hat Enterprise we know today, which gave birth to White Box Enterprise Linux, Scientific Linux, and CentOS. WBEL and SL slowly faded and CentOS won out. And then CentOS, eventually folding into RedHat, promised everyone that it had the support of Red Hat - now part of IBM. Well, now we're back to the big announcement: Red Hat (IBM) is going to mix it up again. And now, as before, come the clones: Rocky Linux has been announced... https://www.reddit.com/r/RockyLinux/comments/ka0qlv/ meet_rocky_linux_new_rhel_fork_by_the_original/ If history is any guide, you'll change a line somewhere in /etc/yum.d and then run yum update to switch over. That's how I switched from WBEL to SL to CentOS, way back in CentOS 3 or 4 days. (I don't even remember which one anymore) The more things change, the more they stay exactly the same... Ben

Missing intel/sof/sof-cml.ri for CentOS 8.3
by Kay Schenk 10 Dec '20

10 Dec '20

Hello all-- I recently did a bulk update from 8.2 to 8.3. I am having some odd issues with it not recognizing my NVIDIA Quadro P1X00 graphics card properly. In graphical mode, it only shows ONE display resolution and also my system can not find firmware -- intel/sof/sof-cml.ri Any idea about what to do flor either of these issues? Thanks. -- "Don't let anyone dull your sparkle." ________________________________________ MzK

dnf script to cherry pick updates and maintain RHEL compatibility
by Frank Cox 09 Dec '20

09 Dec '20

Here's an idea, though I don't know if it would be practical. I assume that at some point everything that goes into RHEL and its "official" updates travels through the Stream ecosystem beforehand. So what about the idea of maintaining (somewhere) a list of official updates to RHEL as they are released, and then have some kind of a dnf enhancement or script that reads that list and updates a local Centos installation using only the rpms on the list and ignoring everything else. Stuff that's released to Stream would be downloaded and installed at the point where it has been released for RHEL and not before. That would (I think) keep your Centos installation in sync with RHEL. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Stream questions
by James Szinger 09 Dec '20

09 Dec '20

I have a couple of questions about CentOS Stream. 1. Is there list for update announcements? Something similar to updates(a)fedoraproject.org. 2. Since both CentOS and EPEL are Red Hat projects, will Red Hat provide an EPEL version compatible with CentOS Stream? Jim

CentOS Stream & Release Notes / Documentation
by Chris Schanzle 09 Dec '20

09 Dec '20

One thing I have not seen discussed is how users will be notified of changes to functionality and new features in CentOS Stream. With Stream being on the leading edge of a release as opposed to following, will there be some mechanism where changes are blogged about, Beta release notes, or something similar? Thanks again to JohnnyH and the rest of the team for a great ride.
