    Sweet, now waiting on CentOS 8 ! Wondering if CentOS 8 will retain RHEL 8 Web Console ?
    and RHEL 8 Universal Base Image
    Definitely looking forward to testing out CentOS 8 where like Red Hat Enterprise Linux 8, will sport updated Linux 4.18 Kernel, glibc 2.28, binutils 2.30, git 2.18, mercurial 4.8 and OpenSSL with TLS 1.3 native support. Finally so updated versions from ancient ones in CentOS 6/7 :D

    Interesting RHEL 8 natively supports Nginx 1.14 (too old for Centmin Mod use) and either MySQL 8.0 or MariaDB 10.3. Centmin Mod will continue to use official mariadb.org's MariaDB 10.3 YUM repo right now and MySQL 8.0 offered by RHEL8 will default to mysql_native_password authentication as some client tools and libraries in RHEL 8 are incompatible with the caching_sha2_password method, which is used by default in the upstream MySQL 8.0 version. MySQL 8.0 support is on Centmin Mod project dev dashboard of wishlist items to do centminmod/centminmod

    About the CentOS 8 release.

    This way of working remains very cumbersome, in my opinion.
    As part of the same company.

    Why would you start rebuilding everything from scratch?
    The source remains the same. Instead of making 2 packages.

    Now they are doing everything one more time.
    Very inefficient.

    yeah now they're part of same company wonder if they do have plans to streamline the process - though I think part of the CentOS proposition is they're independent of RHEL to some extent - well yeah that was in the past somewhat.

    Yup
    Cockpit Web Console is in fact the RHEL 8 Web Console.


    The source is already available at:
    Tree - rpms/cockpit - CentOS Git server
    Could be available in the near feature as the nodejs-10 source from the RHEL example is available at:

    Releases - rpms/nodejs - CentOS Git server

    Problem is that Software collections version 7 so far, is very poorly maintained by CentOS. So I expect little of it, to be honest. As RHEL 8 Universal Base Image is without PR talk, in fact an upgraded Software Collections or Application Streams.... You name it. To run the latest bits.

    I will probably only move to Centos 8, when 8.2 or 8.3 gets released.

    Too much to mention of EL 5 and 6 clusters (MC) over here :) and they will only be migrated if the End of Extended Life-cycle Support is game over.

    Personally: I don't like >= EL7 as it is kind of bloatware ish.
    Systemd, NetworkManager, firewalld, dnf and dnf-makecache:mad:

    And all other not on said useless boot by default Oompa-Loompa services.

    All the mentioned newer versions I posted above = better performance particularly for kernel and glibc versions and not to mention using GCC 8.2 by default.

    Phoronix benchmarked RHEL 8 on Intel Cascade Lake server, dual Intel Xeon Platinum 8280 "Cascade Lake" Gigabyte server compared to CentOS 7.6 (RHEL 7.6), Ubuntu 18.04.2 LTS, Ubuntu 19.04, Fedora Server 29, Fedora Server 30, openSUSE Leap 15, and Clear Linux 29250 https://www.phoronix.com/vr.php?view=27827 :) Some improvements over CentOS 7 while there's a few regressions too.

    We have a liftoff...
    The build-up of Centos 8 has started.

    Obviously very cumbersome, via GIT.
    While the SRPM's are simply available for business customers.
    So also for Red Hat's own CentOS.

    Given the previous time of publication for CentOS 7.0.
    CentOS 8.0 will be issued approximately +- a month after releasing RHEL 8.
    T minus 27+ days and counting :joyful:

    Nice - looking forward to Centmin Mod Nginx/PHP-FPM benchmarks on CentOS 7 vs CentOS 8 :)

    Thanks for sharing that :)

    interesting observation on RHEL8 RHEL 8, and potentially CentOS 8, lack "/usr/bin/python" — Linux Network Development

    Simply put %if 0%{?rhel} == 8 in your .SPEC and you're done.

    1. Build your own repo, createrepo and put it on your own DVD, stick or what else.
    2. Sever on 1 GB of RAM in 2019 is asking for problems anyway.
    3. Mock is available on Fedora so kinda easily to rebuild.

    Easy to solve. Wonder if these are serious questions from the maintainers in question?
    Or that they simply disagree with the RHEL 8 path that has been taken by Red Hat.

    Pff and again they work simultaneously on an unofficial RHEL 8 armhfp (ARM32, ARMv7 - aka armv7hl) clone.
    Besides the official bits. I suspect again a slowdown just like with the EL7 release.

    I really wonder why they don't just convert official bits only.
    Is this to create extra work to retain their job?

    Seems as hughesjr is the only package creator, wtf is the rest of the team is doing?

    I guess it's just folks reactions to something that is different.

    I agree. Does that lump in ARMv8 too ? I wouldn't mind some focus there as I wouldn't mind making Centmin Mod eventually support CentOS 7/8 ARMv8 cpus too.

    Armv8 is officially supported by Red Hat's '64-bit ARM architecture'. This one is part of CentOS 32 bit support. Just like CentOS 7 x86 32 bit. A joke if you ask me.

    CentOS SIG's are great. If you need XEN or something like that. But changing something fundamental like rebuilding x64 to x86 is one bridge to far.

    Red hat doesn't support it for nothing, either. That has been considered well.

    Always pleasant to experience the look and feel of a new product?
    See here the CentOS 8 default background which will be quite recognizable over a time.:)
