-=========================
-
-The ``image-prelink`` class enables the use of the ``prelink`` utility
-during the :ref:`ref-tasks-rootfs` task, which optimizes
-the dynamic linking of shared libraries to reduce executable startup
-time.
-
-By default, the class is enabled in the ``local.conf.template`` using

 **A:** The first most obvious change is the system stripping debug symbols from
