[Nix-dev] Easiest way to deploy a nix-built application with Charon?

[Shea Levy]

Hi Luke,

If your application is something that should go into $PATH, you should 
put it into enviroment.systemPackages, e.g. environment.systemPackages = 
[ (import /path/to/my/package.nix) ]; On the other hand, if it's 
something that only needs to be run by a systemd unit, you'll need to 
write your own unit, e.g

systemd.services."my-service" = {
   # systemd unit information here...
   serviceConfig.ExecStart = "${import 
/path/to/my/package.nix}/bin/command arg1 arg2";
};

I can help in more detail if you can describe your specific application 
and how it's deployed.

Thanks,
Shea
