Wish I would have found this about two days ago but created this which compares well. https://gist.github.com/weex/265cfc6d1f05589c56d580f24089ecd5

With the .env.production chmod, does it get written there by default? I didn't think it did but my notes were missing that part and it's left me wondering where exactly it was saved. I replaced the file manually out of an abundance of caution and haven't had a chance to go back and test.
