Debian 1 story

Within Operating Systems & Release Families, Debian deserves its own scope because its behavior, configuration, and compatibility questions are distinct from the surrounding topics. Important context includes APT package management, stable release, system updates, and package dependencies; these concepts help explain what the technology controls, what it depends on, and how it interacts with the larger platform. By keeping the scope on Debian, readers can understand the role of this layer without confusing it with broader platform maintenance or unrelated faults.
