Overview

This inspects the Vagrantfile provided by the box (if one was provided) and checks if it set the ‘base_mac` value. If it did, a warning will be generated to the user.

NOTE: This action is merely a “best effort” at providing the warning. It is using non-public Vagrant internals to inspect box Vagrantfile. As such, any errors encountered will be ignored with only a debug log.
