Configuration files for my personal server, powered by NixOS.

Modules

The configuration is sliced into different files, per category:

  • ZFS pool configuration: hardware-configuration.nix
  • Network configuration: networking.nix
  • Synchronization and backup services: datasync.nix
  • Web services and reverse proxy: webstack.nix
  • Development tools: devops.nix
  • Smartd: monitoring.nix
  • Systemd services and timers: periodic.nix
  • Curated articles: information.nix

All the modules are imported in configuration.nix
