Not running at starttup

Everything's working great when manually run with `$ npr-one` but after using `$ pm2 start npr-one && pm2 save` the errors shown by `$ pm2 logs npr-one` lead to:

```
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
^
SyntaxError: Unexpected token [
```

Not sure why the bracket is acceptable when I run it but a syntax error through pm2.

Start with the npr-one entry point and compare its manual invocation with the `pm2 start npr-one && pm2 save` flow. Inspect the errors from `pm2 logs npr-one`; done when the saved startup process launches without the reported JavaScript syntax error.
