-    # The base class for a "system." A system represents an installed
-    # operating system on a given box. There are some portions of
-    # Vagrant which are fairly OS-specific (such as mounting shared
-    # folders) and while the number is few, this abstraction allows
-    # more obscure operating systems to be installed without having
-    # to directly modify Vagrant internals.
-    #
-    # Subclasses of the system base class are expected to implement
-    # all the methods. These methods are described in the comments
-    # above their definition.
-    #
-    # **This is by no means a complete specification. The methods
-    # required by systems can and will change at any time. Any
-    # changes will be noted on release notes.**

-      #
-      # **Warning:** If a return value which subclasses from {Base} is
-      # returned, Vagrant will use it as the new system instance for the
