Ryan Yin c4a00e507c fix(nixpak): pass the session TZ through to sandboxes
ICU takes the zone name from the /etc/localtime symlink target path. A bind
mount turns it into a plain file, which keeps the TZif data but loses the
path, so the only identifier left is the ambiguous "CST" abbreviation that
ICU reads from the file and maps to America/Chicago.

Export TZ from time.timeZone and pass TZ/TZDIR through the nixpak env
allowlist.

System hardening modules (kernel baseline, AppArmor, app sandboxes) live under ../hardening/.

Module Categories

1. Base Modules (base/)

Common configuration shared between NixOS and macOS:

  • System fonts and localization
  • Essential packages and tools
  • Basic security settings
  • User management
  • Package overlays

2. macOS Modules (darwin/)

macOS-specific configuration:

  • macOS applications and system settings
  • Security configurations tailored for macOS
  • SSH and system-level settings
  • Package compatibility fixes

3. NixOS Modules (nixos/)

Platform-specific NixOS configuration:

  • Base: Core system settings and services
  • Desktop: Desktop environment and GUI applications
  • Server: Server-specific optimizations and services

Usage

There is no automatic platform detection. Each host's entry under outputs/<system>/src/ lists its imports explicitly:

  • NixOS Systems: import nixos/ modules
  • macOS Systems: import darwin/ modules
  • Both: import base/ modules for shared configuration
