Overview

This built-in middleware exports and mounts NFS shared folders.

To use this middleware, two configuration parameters must be given via the environment hash:

- `:nfs_host_ip` - The IP of where to mount the NFS folder from.
- `:nfs_machine_ip` - The IP of the machine where the NFS folder
  will be mounted.
