Remediation

Configure RHEL 10 to remove all software components after updated versions have been installed.

Edit the file "/etc/dnf/dnf.conf" by adding or editing the following line:

 clean_requirements_on_remove=True

Note: Any of the following are acceptable: "1", "true", or "yes" (keywords containing letters are case insensitive).
