Does Meteor copy the local NPM packages?

Hey,
just have a question about how Meteor handles NPM packages during the build process. If I run meteor build …/built, will Meteor copy all packages from the node_modules folder into the build bundle, or will it run npm install and download all packages again for the build bundle?

I’m asking the question because I’m using https://www.npmjs.com/package/geoip-lite. In this case, I can run npm run-script updatedb to update the database. If I run it on my dev machine and then execute meteor build, will the build bundle have the updated database or the default one of the package?
