description = ''
The path to the nixpkgs source used to build a system. A `base` package set
is required to be set, and can be specified via either:
1. `options.nodes.base` (default `base` used for all systems)
2. `options.nodes.nodes.<name>.base` (takes prescedence over `options.nodes.base`)
This can also be optionally set if the NixOS system is not built with a flake but still uses
pinned sources: set this to the store path for the nixpkgs sources used to build the system,
as may be obtained by `fetchTarball`, for example.
Note: the name of the store path must be "source" due to
<https://github.com/NixOS/nix/issues/7075>.

The path to the home-manager source. A `homeManager` flake reference

1. `options.nodes.homeManager` (default `homManager` used for all systems)
2. `options.nodes.nodes.<name>.homeManager` (takes prescedence over `options.nodes.homeManager`)
