Worked on enhancing deployment documentation for appliance clustering in the Checkmk/checkmk-docs repository by generalizing network interface naming conventions. Focused on clarifying that interface names such as LAN1 and eth0 are hardware-dependent examples, which reduces ambiguity and potential misconfigurations during deployment. The update was implemented as a concise, review-friendly change in a single commit, emphasizing accuracy and maintainability. Utilized asciidoc for technical writing and documentation, ensuring that both the documentation and configuration examples reflect the variability of hardware environments. This approach improves onboarding for new deployments and provides clearer, more reliable guidance for configuring network interfaces in clustered appliances.
