This issue is purely informational, you do not need to take any action. Thank you for your work maintaining image-builder in EPEL 9. Red Hat considers this package important enough to promote it to official RHEL. It will be part of RHEL 9.7. Please do not update image-builder in EPEL 9 so the RHEL version can have a higher version and release. When RHEL 9.7 is released, EPEL automation will remove image-builder from EPEL 9 and close this bug.
image-builder is now in RHEL9 as of RHEL 9.7. It has been retired from EPEL9. It will take a day or two before it is out of the epel9 repositories and mirrors.
