```ruby
class NFSStep < Step
  add_alias :nfs

  def run
    log "Mounting  #{config['host']}:#{config['remote_path']}  at  #{config['local_path']}"
    `mount -t nfs #{config['host']}:#{config['remote_path']} #{config['local_path']}`
  end

  def unrun
    log "Unmounting  #{config['host']}:#{config['remote_path']}  from  #{config['local_path']}"
    `umount #{config['local_path']}`
  end
end
```

Move `NFSStep` into `WRKFLO` module, update configurations
user
```ruby
module WRKFLO
  class NFSStep < Step
    add_alias :nfs

    property :host,         required: true, type: String
    property :remote_path,  required: true, type: String
    property :local_path,   required: true, type: String

    def run
      log "Mounting  #{config.host}:#{config.remote_path}  at  #{config.local_path}"
      `mount -t nfs #{config.host}:#{config.remote_path} #{config.local_path}`
    end

    def unrun
      log "Unmounting  #{config.host}:#{config.remote_path}  from  #{config.local_path}"
      `umount #{config.local_path}`
    end
  end
end
```
