NixOS Configuration Context

Architecture

• Using flakes.
• System-level configuration and user-level configuration (Home Manager) are mixed up in the same files.
• 'hosts/' - Main configuration and hardware configuration for each of the hosts.
• 'libs/' - Declarations and reusable content.
• 'modules/apps/' - Application-specific configuration.
• 'modules/harwdare/' - Hardware-specific configuration.
• 'modules/services/' - Configuration for services running on the hosts.
• 'modules/system/' - Configuration for large subsystems (for example graphical subsystem) involving multiple apps and/or system configuration.
• 'secrets/' - encoded secrets (using ragenix).
