Learn how sustaining engineering teams maintain security and compliance for legacy Linux distributions in this 17-minute conference talk from DevConf.IN 2026. Discover the critical engineering processes behind supporting decade-old Linux releases through modern security patches while preserving system stability for enterprise and government workloads. Explore the technical challenges of identifying, triaging, and backporting CVE fixes into aging codebases without breaking ABI/API compatibility, including real-world examples of delivering high-severity patches within five business days. Gain insights into the specialized work of patching outdated kernels, libraries, and dependency chains that differ significantly from upstream versions, with practical examples from printing, networking, security, and cryptography components. Understand how this sustaining engineering approach enables governments and regulated institutions to maintain regulatory approvals and secure infrastructure when system upgrades are operationally challenging or impossible, and learn why major vendors like Red Hat, openSUSE, Ubuntu, Debian, and Oracle are investing heavily in extended lifecycle maintenance programs.
