From fd0325324f1f86684f3753a4d51e7937d8744a11 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 27 Aug 2013 12:02:58 +0000 Subject: [PATCH] image: ensure that /dev/console exist in rootfs images Linux expects that the /dev/console node is present in the rootfs image. Create the node in rootfs images, in order to make std{in,out,err} usable even in early init process. Note: tar.gz and cpio.gz images are not handled yet.
