From 7191bf0492168a2b488eb3ce52129def996b40ea Mon Sep 17 00:00:00 2001 From: Sen Jiang Date: Mon, 22 Jan 2018 15:01:48 -0800 Subject: Add update_channel field to bootloader_message_ab. The update_channel field is used to store the Omaha update channel if update_engine is compiled with Omaha support. We need it to be in misc to persist through factory reset.
