Whether or not to enable the nixarr module. Has the following features:
- **Run services through a VPN:** You can run any service that this module
supports through a VPN, fx `nixarr.transmission.vpn.enable = true;`
- **Automatic Directories, Users and Permissions:** The module automatically
creates directories and users for your media library. It also sets sane
permissions.
- **State Management:** All services support state management and all state
that they manage is located by default in `/data/.state/nixarr/*`
- **Optional Automatic Port Forwarding:** This module has a UPNP support that
lets services request ports from your router automatically, if you enable it.
It is possible, _but not recommended_, to run the "*Arrs" behind a VPN,
because it can cause rate limiting issues. Generally, you should use
VPN on transmission and maybe jellyfin, depending on your setup.
The following services are supported:
- [Jellyfin](#nixarr.jellyfin.enable)
- [Lidarr](#nixarr.lidarr.enable)
- [Prowlarr](#nixarr.prowlarr.enable)
- [Radarr](#nixarr.radarr.enable)
- [Readarr](#nixarr.readarr.enable)
- [Sonarr](#nixarr.sonarr.enable)
- [Transmission](#nixarr.transmission.enable)
Remember to read the options.
