From 00ddacc1a1860bf777ba32ac0ece7a566c97bf48 Mon Sep 17 00:00:00 2001 From: Mark Langsdorf Date: Tue, 10 Sep 2013 15:20:23 -0500 Subject: autoboot: add an option to override keyed autoboot As originally implemented, setting the AUTOBOOT_KEYED config option will prevent users from breaking into the autoboot script with ctrl-c. Restore that option with a new config symbol.
