From 27d69d25612e857268492678b86aa88e8ea924ac Mon Sep 17 00:00:00 2001 From: Imran Khan Date: Tue, 17 Dec 2019 05:59:28 -0800 Subject: [PATCH] uboot-envtools: check for config prior to append In the rare event a pre-populated fw_env.config exists in the rootfs prior to firstboot, calling fw_setenv after the system has initialised will annihilate the devices environment due to two identical lines in fw_env.config. Check for existence prior to blind appendage.
