📜 The History and Founding of Debian
Debian was created in August 1993 by Ian Murdock, a Purdue University student, who introduced the Debian Manifesto — a call for a community-driven, transparent, and open Linux distribution.
The name Debian merges Debra (his then-girlfriend) and Ian.
“Debian will be created openly, in the spirit of Linux and GNU.” — Ian Murdock
Funded initially by the Free Software Foundation (FSF), Debian quickly became a foundational GNU/Linux system respected for its organization, philosophy, and long-term vision.
🧬 What Sets Debian Apart

- Debian Free Software Guidelines (DFSG): All packages comply with Free Software principles.
- Three-Tier Branches: Stable, Testing, and Unstable branches support all user levels.
- Multi-Architecture Support: Works on more hardware platforms than most distros.
- Rock-Solid Stability: Known for reliable releases.
- Social Contract: Transparent development and respect for user freedom.
