You can run 'charon create -I
nixos=<location-of-machine-specific-nixos> -I
nixpkgs=<location-of-machine-specific-nixpkgs> network.nix' . It will
make nix evaluation use the specified nix-path entries.
>From the man page:
Options
-I path
Add path to the Nix expression search path for all future
evaluations of the deployment specification. Charon stores
path in the state file. This option may be given multiple
times. See the description of the -I option in nix-
instantiate(1) for details.
Hope that helps,
Cheers,
Rob
