Synopsis: mkNodes _systemConfigurations_ _extraConfig_
Generate the `nodes` attribute expected by deploy-rs
where _systemConfigurations_ are `nodes`.
_systemConfigurations_ should take the form of a flake's
_nixosConfigurations_. Note that deploy-rs does not currently support
deploying to darwin hosts.
_extraConfig_, if specified, will be merged into each of the
nodes' configurations.
Example _systemConfigurations_ input:
```
{
hostname-1 = {
fastConnection = true;
sshOpts = [ "-p" "25" ];
};
hostname-2 = {
sshOpts = [ "-p" "19999" ];
sshUser = "root";
};
}
```
