Author: kevans Date: Sun Feb 25 16:29:02 2018 New Revision: 329986 URL: https://svnweb.freebsd.org/changeset/base/329986 Log: lualoader: Invalidate the screen from menu perspective upon mnu exit In the common case, this will effectively do nothing as the menu will get redrawn as we leave submenus regardless of whether the screen has been marked invalid or not However, upon escape to the loader prompt, one could do either of the following to re-enter the menu system: -- Method 1 require('menu').run() -- Method 2 require('menu').process(menu.default) With method 1, the menu will get redrawn anyways as we do this before autoboot checking upon entry. With method 2, however, the menu will not be redrawn without this invalidation. Both methods are acceptable for re-entering the menu system, although the latter method in the local module for processing new and interesting menus is more expected.
