Production-Ready Debian Installation: Network Installer, LVM, Minimal Setup

In the first lesson of the "Debian Mastery" series, we cover how to install Debian in a production-ready configuration. This guide focuses on using the network installer for repeatability, setting up LVM for flexible storage, and selecting only essential packages—no desktop or recommended extras. The process includes custom partitioning, initial system configuration (hostname, timezone, NTP), and a basic firewall. These steps build a solid foundation for any production server. The course aims to teach IT professionals efficient, no-filler skills applicable to DevOps, sysadmin, and cloud engineering roles.
