    RPM packages seems to be good to go. Simple. Other wise you won't officially sign them.

    Problem is that x86_64, ppc64le/aarch64, unofficial arm and 32 bit is in parallel.
    Better the most important first. Who is running CentOS 32 bit and/or CentOS arm7 anyway?

    They can be counted with one hand.

    True though i wonder what cpu/hardware those build servers are on ? I remember reading on twitter one developer switching from ancient xeon and AMD pre-zen architecture based build servers to AMD Threadripper and Ryzen 3900X and reducing their build times by 50+ % and reducing their electricity usage by 66+ % !

    I wonder why they don't make much use of the benefits it offers when you are part of an organization like Red Hat.

    For example:
    Why would you develop and set up your own building system if the parent company already has everything?

    This costs a lot of unnecessary time, effort and money.

    They are constantly re-inventing their own wheel.

    Yeah I suspect developers like to do and configure/setup things their own way - I know I do :D

    Jup CentOS 8 does support live kernel patching.
    Kpatch is suppported since CentOS 7.
    https://git.centos.org/rpms/kpatch/releases

    However it is not about Kpatch, the mechanism to patch the Kernel code.
    It is about the patches self.

    And that is the problem, if you want to do that yourself you will have to do everything yourself.
    This takes a lot of time and therefore money.

    A cheap alternative is Kernelcare. This is based on Kpatch and works properly.

    I thought by enabling live kernel patches that Centos team will release them and deploy them every x hours as Ksplice does.....

    In other words release work is about the start as there is a GA (General Availability) tree.
    Returning to the earlier statement by Karanbir Singh,
    I bet on a release in the week of August 26 or with some luck end of week August 19.

    I suspect the CentOS 8 finall bits itself (all in with ISOS and the existing tree) will be finished next week (week of August 19).

    After which a mid-week or week period is needed to quietly give all mirrors (a lot) time to sync everything.

    Yeah getting close. EPEL 8 for RHEL 8 is out just need EPEL 8 for CentOS now https://twitter.com/CentOSProject/status/1161702263443939328

    https://lists.fedoraproject.org/arc....org/thread/HXFHAPXPG2FX4NHP2WDNE3J3JXE53LML/

    Looks like RHEL8 and CentOS 8 and CentOS 7.7 and EPEL 7/8 will have alot of breaking changes due to different python packages and names between these 3 OS versions native python offerings and what EPEL 7/8 will support

    Python dependencies problem is only the beginning.
    Biggest EPEL 8 problem is, if you ask me: Red Hat Enterprise Linux 8 Application Streams.

    For example EPEL7 PHP memcached is build against EL7 PHP 5.4.
    Is and will be always the same for EL7, EL7.1, EL7.2 etc.

    With EL8 streams you have new versions of applications (PHP, Apache, MariaDB, Nginx etc).

    Problem is that EL8.0 streams is build against PHP 7.2 but EL8.1 is build against PHP 7.3, but PHP 7.2 is still supported until retirement on May 2021.

    So EPEL8 PHP memcached should be build against all currently supported PHP versions.

    Currently EL8.0 supports only one PHP version.
    But after EL8.1 there are 2, and after EL8.2 maybe 3 and then 4 etc.

    Gigantic more work and this example is only about 1 PHP and only 1 PHP extension.
    There are a lot more Application streams and thousands of EPEL packages.

    Without good management EPEL8 becomes a gaotic mess.

    Furthermore about Red Hat Enterprise Linux 8 Application Streams.
    My biggest problem related to Application Streams. Is mission critical.

    Mission critical and the Application Streams Release Life Cycle don't go together hand in hand as benefit. For example PHP. The retirement date of EL8 PHP 7.2 is
    May 2021. That is 2 years. Way too short.

    For instance. We are only now just starting to careful use EL7 in mission critical setting.
    And still not on core systems.

    5 years after releasing the first EL7 bits.

    As described more often, the use of new software is not always possible.
    Not that we do not want it, it cannot be otherwise for various factors.

    The solution from Red Hat would be very easy.

    BaseOS, Application Streams LTS (with the same lifetime as the core (BaseOS)) and Application Streams EL8.1, EL8.2 etc.

    In my opinion, the current way of software does not make various real-time and mission-critical Red Hat customers happy.
