During their recent work, Cahu enhanced SELinux documentation for SLE16 in the SUSE/doc-modular repository, restructuring content and expanding technical guidance to improve clarity for administrators and developers. They addressed configuration pitfalls by correcting semanage booleans usage and refactoring instructions, adding detailed sections on policy management, contexts, and troubleshooting. In os-autoinst-distri-opensuse, Cahu stabilized SELinux-enabled test environments for OVS/IPsec and yast2-proxy modules, focusing on correct SELinux labeling and context preservation to prevent test failures. Their contributions combined technical writing, system administration, and testing skills, using Markdown and Perl to deliver maintainable solutions that reduce onboarding time and test flakiness.
