Contributions summary:Zdeněk's contributions primarily involve modifying SELinux policy for the Fedora operating system. They implemented changes to allow various services and utilities, such as arpwatch, cockpit, esmtp, systemd, strongswan, spamd_update, and others, to function correctly within the confines of SELinux. These modifications involved labeling files and directories with specific security contexts, enabling file transitions, and adjusting permissions to address security-related denials. The impact of these changes is increased security by ensuring applications operate within the defined security boundaries.
