-	  If you say Y here the resulting Xen will include debugging info
-	  resulting in a larger binary image.

+	  Saying Y will increase the size of the xen-syms and xen.efi

+	  limited, you may want to install a stripped variant of xen.efi in
+	  the EFI boot partition (look for "INSTALL_EFI_STRIP" in
+	  docs/misc/efi.pandoc for more information - when not using
+	  "make install-xen" for installing xen.efi, stripping needs to be
+	  done outside the Xen build environment).
