In RHEL 8.4 and later, the s390utils-base package is split into an s390utils-core package and an auxiliary s390utils-base package. As a result, setting the RHEL installation to minimal-environment installs only the necessary s390utils-core package and not the auxiliary s390utils-base package. If you want to use the s390utils-base package with a minimal RHEL installation, you must manually install the package after completing the RHEL installation or explicitly install s390utils-base using a Kickstart file.
