Potential EX200 package management tasks
- Configure RPM repositories: Set up, enable, or modify software repository definitions and access remote or local repository sources.
- Install and Remove RPM Packages: Use DNF or RPM utilities to search for, install, query, verify, and uninstall RPM software packages.
- Install from Local or Remote Sources: Install software packages directly from the local file system, remote repositories, or the Red Hat Content Delivery Network.
- Manage Flatpak Packages: Configure Flatpak remote repositories and install, update, or remove Flatpak applications (featured in recent RHEL versions).
- Persistence After Reboot: Ensure all package management configurations, enabled repositories, and service adjustments persist across system reboots without manual intervention.
