title: Writing to file on the server in Meteor [1.0.0] (without losing the files every build)
body: <p>The issue I've been having is that <code>fs.writeFile</code> writes to the <code>build</code> folder under <code>.meteor</code> and when rebuilt is lost.</p>
  
  <p>The <code>Assets</code> api doesn't seem to allow for writes. All I'm looking to do is write some text to a file and load it up upon next startup.</p>
  
  <p>Specific use case: Steam returns data for a <code>shaSentryfile</code> within their API that needs to be reused on subsequent requests, otherwise the authentication process is partially manual.</p>

  <p>I've thought about using some external storage service like S3, but this is such a simple scenario--it's only the one file--but i'd like to understand how files like this should be managed in Meteor.</p>
