Worked on the netbirdio/netbird repository to enhance the installation script, focusing on secure GPG key handling and reliable permission management. The update introduced explicit file permission settings for GPG keys, ensuring owner read/write access and read-only access for others, which aligns with security best practices. Leveraging Shell scripting and DevOps skills, the developer incorporated sudo-based permission changes within install.sh to standardize behavior across diverse environments. This approach improved onboarding reliability by reducing install-time failures related to permissions. The work was traceable to a specific commit, supporting auditability and preparing the project for broader, more secure deployments in production environments.
