This issue is purely informational, you do not need to take any action. Thank you for your work maintaining image-builder in EPEL 10. Red Hat considers this package important enough to promote it to official RHEL. It will be part of RHEL 10.1. Please do not update image-builder in EPEL 10 so the RHEL version can have a higher version and release. When RHEL 10.1 is released, EPEL automation will remove image-builder from EPEL 10 and close this bug.
image-builder is now in RHEL10 as of RHEL 10.1. It has been retired from EPEL10 and EPEL10.1. It will take a day or two before it is out of the epel repositories and mirrors.
