Workaround vagrant-vbguest plugin fail due to NoSuchMethod error on `File.exists?`

restore_file_exists_method.rb

# Place this blurb at the top of your Vagrantfile to allow the unpatched
# version of the Vagrant vagrant-vbguest plugin to properly execute
# in newer Ruby environments where File.exists is no longer supported
#
# Extend the Ruby File class to restore the deprecated exists method
# calls File.exist instead
unless File.respond_to?(:exists?)
  class << File
    def exists?(path)
      warn "File.exists? is deprecated; use File.exist? instead." unless ENV['SUPPRESS_FILE_EXISTS_WARNING']
      exist?(path)
    end
  end
end
