    # The URL fetcher uses a Tempfile to retrieve the vendored
    # profile, which creates a file that is only readable by
    # the current user. In most circumstances, this is likely OK.
    # However, in environments like a Habitat package, these files
    # need to be readable by all users or the Habitat Supervisor
    # may not be able to start InSpec correctly.
    #
    # This method makes sure all vendored files are mode 644 for this
    # use case. This method is not called by default - the caller
    # vendoring the profile must make the decision as to whether this
    # is necessary.
