    Only hope CentOS 7 backports stuff to 3.10 Kernel then. Though it seems Facebook is all in on CentOS 8 Stream FOSDEM 2021 - Desktop Linux Management at Facebook

    One idea is to install Proxmox on Zen3 dedicated server, with compatible Kernel, and then install on the created Proxmox slice Centos 7 /w EL Repo Mainline kernel and Centminmod over that?

    I will try @buik's method from above, but I am not that confident on my sysadmin skills, so I have the Proxmox way as a back up.

    Just a thought, I will make separate thread for that so I won't spam this thread.

    I think the introduction was written by Fosdem and not the presenter himself. When you look at the presentation. It is all about desktops at Facebook. Not servers. 0 reports about servers in that presentation.

    https://fosdem.org/2021/schedule/ev...2021_Desktop_Linux_Management_at_Facebook.pdf

    Facebook seems still on EL7.
    Facebook's GitHub confirmed that. 11 days ago the last update. Definition EL7.

    facebookincubator/rpm-backports

    It seems very unlikely to me that Facebook would put its main site on a rolling server distro. With possible API changes and semi tested packages every day. Not going to happen.

    My option list would be:

    1. Try boot the server with the UEK boot ISO: OL7U9 x86_64-boot-uek.iso

    2. Is this server hardware a must have?
    This is an ultra new server. Where the hardware is supported by only a few OS suppliers.

    3. If you're going to virtualize with Proxmox VE.
    The latest Proxmox VE is on Kernel 5.4 LTS so verify if it is supporting Zen 3.
    As Zen 3 is only on kernel 5.10 and up.
    Unless backported by Debian or Proxmox, it is unfortunately not an option, not even as a backup.

    Well CentOS 8 Stream change announcement did say Facebook will be a major contributor to CentOS 8 Stream development so it's probably something that is in the works and not 100% yet.
    Yeah even that 5.10 Linux Kernel is only starting to add AMD Zen3 support. So I expect issues until later maybe, 5.11+ Linux Kernel if we're lucky. Probably work waiting a bit more for AMD Ryzen 5000 series Zen3 Linux testing.

    That's right. On the desktop.
    From the same presentation:

    This collaboration and addition in Fedora (F) is of course directly reflected in Fedora.
    After all, new features are always tested according to the established pattern: Fedora > CentOS Stream > RHEL. As CentOS Stream is RHEL beta or RHEL what it should be after some time.

    For servers, it looks like Facebook is using their own CentOS 7 Stream.

    Using BaseOS EL7 with own packages branded as FB6 distro.
    Like kernel 5.6 and up, patched systemd, python3 etc. As can be reviewed in Facebook's GitHub.

    It seems to me that this will also be the case with CentOS 8 and FB7.
    CentOS 8 BaseOS stable with own packages.

    Whether you should call this a major contributor? I'll leave that in the middle.

    Yup. Depending on the server task and the degree of importance of the server.
    I would even use only certified dedicated hardware.

    Nothing is as annoying as it should work. Only to find out that it doesn't work.
    And you have to work on drivers and kernel yourself.

    We had just started rolling out CentOS8 at work, and we've now had to stop the rollout.

    I've got a test VM running with AlmaLinux Beta, and I'm making use of the RedHat Developer licence to get the 16 licence entitlements.

    Got my Laptop and jump VM running RHEL8

    Got Centrify central authentication working with AlmaLinux using their RedHat RPMs, and so far looking like a good alternative.

    Ah yes you touched on another gotcha - driver support !
    Bet that was fun! So you're going to stick with CentOS 8 for the already deployed servers or switch those over too whatever OS you end up choosing ?

    Nice, reminds me to make use of my RedHat Developer account :) Haven't had time to look at AlmaLinux Beta yet - hopefully will soon once my client work eases up - had a record busy January 2021!!!

    Ah Intel i7 5600U cpu there, for a moment thought you had a laptop with AMD Ryzen 5600 cpu :D

    Just saw that too.

    Is that a possible option for CM?

    Thanks for the heads up. Interesting !
    Yeah Centmin Mod is an open source project so would be eligible I believe. Though wouldn't make much sense in having Centmin Mod sites and development on RHEL, when most Centmin Mod users wouldn't be using RHEL.

    Sorry to report it but I don't think so.

    From the Red Hat article:
    For the development of Centminmod @eva2000 should be able to qualify for development server licenses.

    To use the developed Centminmod software as individual or company falls outside of the scope.
