CentOS Hyperscale SIG Formed two years ago by a group of engineers from Facebook, Twitter, and other hyperscale companies, they worked on making optional changes to CentOS Stream to better adapt the Linux distribution to their internal needs.Hyperscale SIG Focused on enabling CentOS Stream deployments on large-scale architectures and facilitating collaboration on packages and tools.

Currently, they have released the 2022 Q4 report,Covers work that occurred between October 1, 2022 and January 8, 2023. Specifically include:

• streamlineuser documentationwebsite and keep its content up to date.
• Working on updating systemd for CentOS Stream 8 and CentOS Stream 9, the latest version is systemd 251.4. It is still working on updating SELinux policies for Hyperscale builds, and updating to systemd 251.4 is not recommended if users need to enable SELinux. Additionally, the systemd 252.4 release is hard at work.
• The Linux 5.14 kernel has been modified and continues to be optimized for its use.
• The container build pipeline is fully automated,container imageis built on the CentOS OpenShift CI/CD architecture and is published weekly at Quay Posted on CentOS Stream 8 and CentOS Stream 9 variants are provided.
• Gained the ability to use KIWI to build operating system images through the CentOS build system.
• The updates of zsh, fish, iperf3, dmidecode, fio, dwarves, kpatch, linuxptp and other software packages are more than those provided by CentOS Stream currently.
• Support for disabling specific RPMs so that they cannot use the RPM’s copy-on-write feature.
• The CentOS Hyperscale SIG’s plans are moving to a new OpenShift instance, using CBS to build their spin images, releasing an updated QEMU in EPEL, and integrating Btrfs transactional updates as an optional feature.
