From 0ebdf34f9a0f023f62305bddcbc8427d36f740b4 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Thu, 25 Oct 2012 13:30:02 -0700 Subject: fri2: Add tiny-init bbappend for devtmpfs and console When using an initramfs, the default for poky-tiny, the kernel cannot automatically mount devtmpfs. Ensure it is mounted. This eliminates the need to create the ptmx device.
