Worked on the openshift/installer repository to streamline operating system support by removing Fedora CoreOS (FCOS) references and aligning the installer exclusively with CentOS Stream CoreOS (SCOS) and other non-FCOS distributions. This involved eliminating FCOS-specific configurations, build tags, and code paths, which reduced maintenance overhead and clarified the OS flavor strategy for future deployments. The changes improved continuous integration reliability and simplified the build system configuration. The work was implemented using Go and YAML, with a focus on installer development and build system management, resulting in a more predictable and maintainable deployment process for non-FCOS environments.
