[OE-core] [PATCH 0/3] Improve devtmpfs and cpio support

[Nathan Rossi]

The following patches improve cpio support as well as improving the
handling of devtmpfs and consolidating the setup of /dev mounts.

Currently udev and mdev handle mounting /dev seperately in their own
init scripts, as well as handling of /dev/pts and /dev/shm. Both however
implement a similar method of mounting and creating directories.
Additionally there is overlap between the udev/mdev init scripts and the
devpts script. This patch attempts to clean up the mounting and setup
so that it is done at a seperate level to the dev manager itself. So
that machines/bsps can override the fstab and have custom /dev mount
setups. This setup also allows for a system which does not use a dev
manager and relies on devtmpfs for /dev nodes, which is useful for very
constrained setups.

Additionally this patch set resolves the need for the devpts init
scripts, and on top of that prepares the /dev/pts interface early enough
for other rc scripts like bootlogd so that there is no need for the
CONFIG_LEGACY_PTYS to be enabled in the kernel.
