Worked on the systemd/systemd repository to improve the accuracy of documentation related to NSS hostname resolution. Focused on aligning the nss-myhostname.xml manual with the current implementation and actual file states, the work addressed discrepancies that could cause confusion for users and maintainers. The update required a careful review of the existing documentation and the underlying C codebase, ensuring that the documentation accurately reflected the system’s behavior without necessitating code changes. This effort enhanced clarity for downstream tooling and workflows that rely on NSS hostname resolution, demonstrating attention to detail and a strong understanding of documentation practices and Linux system internals.
