From a74e0bf51adcc867b73fc44050eb9bde985c9cba Mon Sep 17 00:00:00 2001 From: Andrea Adami Date: Sun, 28 Feb 2016 01:09:19 +0100 Subject: [PATCH] main.c: revert check on console device Fix kernel panic because of the missing /dev/console. Revert Yocto-specific : "check console device file on fs when booting". The initramfs used in this kernel needs to be of the smallest possible size so we save a few kb by deploying an empty /dev which is populated after boot by the init (kexecboot checks and recreates the devices with or without devtmpfs).
