I have a `meteor-up/mupx` deployment with a page in the Meteor `/public` folder, `./public/index.html`

I can load the page successfully from a url that is something like this:

`http://my-app.com:3333/index.html`

But I would like to make this page the default page for the domain, so I can access it like this:

`http://my-app.com:3333/`

I added the following in my Meteor `bootstrap.js` file

```
WebApp.connectHandlers.use("/", function(req, res, next) {
  var err, error, error1, filepath0, filepath1;
  if (req.originalUrl !== '/' || req.method !== 'GET') {
    return next();
  }
  try {
    filepath0 = process.env.PWD + '/public/index.html';
    // filepath1 = '/opt/my-app/current/bundle/programs/web.browser/app/index.html';
    fs.statSync(filepath0).isFile();
  } catch (error) {
      err = error1;
      console.log("file not available, path=" + filepath);
      return next();
  }
  fs.readFile(filepath0, function(err, buf) {
    var eTag, err, headers;
    try {
      eTag = crypto.createHash('md5').update(buf).digest('hex');
      if (req.headers['if-none-match'] === eTag) {
        res.writeHead(304, 'Not Modified');
        return res.end();
      }
    } catch (err) {
      eTag = null;
    }
    headers = {
      'Content-Type': 'text/html',
      'ETag': etag
    };
    res.writeHead(200, headers);
    return res.end(buf);
  });
});

```

This works fine from my standard Meteor project. But when I deploy via `mupx` I get an exception because the `index.html` file is not in the same location.

How can I `fs.readFile()` the file which was located in `/path/to/Meteor/public` after it has been deployed via `mupx`

from `Meteor`, I could use `filepath0 = process.env.PWD + '/public/index.html'

But the same code from `mupx` gives `filepath0 = /bundle/bundle/public/index.html`, and the file is not there.

from the `mupx` server, I can actually `ls` the file at `filepath1`, but even using that value does not work.
