Debian 12 LTS Is a Coverage Audit, Not a Snooze Button
Debian 12 is under LTS through June 2028, but the date does not cover every package or architecture. Audit the host before deciding to stay or upgrade.
Systems & Ops
Reliability, monitoring, architecture, verification, access, and maintenance for systems that need to stay understandable and recoverable.
