Worked on the major/cloud-init repository to enhance network provisioning reliability by updating the DHCP connectivity check process. Addressed a bug in the ephemeral DHCP path by replacing the deprecated has_url_connectivity function with the newer _check_connectivity_to_imds, ensuring more deterministic network readiness before DHCP discovery. The approach involved Python-based refactoring, including the removal of unused imports and obsolete tests, which streamlined the codebase and reduced maintenance overhead. Focused on network configuration and unit testing, the work improved the stability of ephemeral environments and contributed to cleaner, more maintainable code by eliminating deprecated logic and minimizing potential sources of test flakiness.
