BTW, I created this story to update the installer from CentOS 7.4 to CentOS 7.6, in case anyone wants to participate.
Thanks for making this Erich , this is a topic that we check on last week meeting and I had the AR to send the mail about the need of 7.6 installers instead of 7.4 . I am happy to see you share my point :) and take the initiative to create the story ( good team work ) Now to clarify the other point of why Erich create the sotory with this justification : The installer is using CentOS 7.4 files, the upgrade into 7.6 is needed. if we read the document of https://git.starlingx.io/cgit/stx-metal/tree/installer/initrd/README we can see There are three prebuilt files that we can update when we need to make changes to the installer: - vmlinuz - The kernel - initrd.img - Initial initrd loaded when the installer boots. Has kernel modules, etc, and loads the squashfs.img - squashfs.img - Provides the rootfs for the installer, which includes components like anaconda When we update the kernel and kernel modules for the installer, we need to update the initrd.img. This is a manual procedure currently and must be done. The initrd is an initial root file system that is mounted prior to when the real root file system is available. The initrd is bound to the kernel and loaded as part of the kernel boot procedure. The kernel then mounts this initrd as part of the two-stage boot process to load the modules to make the real file systems available and get at the real root file system. If we don't do this the symbols will not link correctly [0] The initrd contains a minimal set of directories and executables to achieve this, such as the insmodtool to install kernel modules into the kernel. My concern las t build meeting was that by using initrd.img wih modules linked to kernel of centos 7.5 and latter on boot installer try to load kernel of centos 7.6 it might gave us some problems hard to debug, it might be clean to use centos 7.6 with its own installer [0] https://www.ibm.com/developerworks/library/l-initrd/index.html Regards Victor Rodriguez

It seems just rpm package is released, but srpm is not released yet. I will keep check it recently.

Seems like that CentOS 7 just announced 1810 release today (guess this is 7.6):

Yup, timing is!
Cindy, can you please put this on the agenda for the next non- openstack Distro meeting.
We also have a topic for the TSC (thanks BruceJ) the following morning, TSC members may want to start weighing in here regarding my initial proposal below, which we can talk more about on Thursday.
Thanks Sau!
thx. - cindy

Folks,
As we move forward into the spring release (Stein based), we will also be dealing with another CentOS update. RHEL has already released the 7.6 Update on Oct 30th, typically we should expect the CentOS 7.6 update shortl, about 30 days after RHEL releases.
We should do the 7.6 Update as we did the 7.5 Update on a feature branch, it took about 2 months last time (including initial setup, rebasing, and de-fuzzing), I expect it will be shorter this time based on our past learning.
We should start out with creating the feature branches (I will work with Dean on this) for stx-integ, stx-root, stx-tools, and stx- upstream repos. When we start the work, we need to remember to rebase the feature branches regularly and check for patch fuzzing issues.
Cindy, can you please put this on your agenda for the next Non- Openstack Distro meeting.
While on the topic of Cento Distro updates, many of you may have heard that RHEL 8 Beta was announced on Nov 14 [0], while this is not a CentOS release we should start thinking about that upgrade as it will be a larger effort as it includes the 4.18 kernel (alas not the 4.19 LTS kernel) along with many other upgrades. We should start a feature branch for CentOS 8 as well to do the updates, This will help reduce some of the patch load from the backported patches. Since we don't know exactly when CentOS 8 will be available this should be a Train-based release target (Fall 2019) (at the earliest)
