to Belden CoreOS. 

.. index:: MACHINE_FEATURES
    
Machine Features
================

CoreOS doesn't define any custom machine feature for now, but the 
:external:ref:`MACHINE_FEATURES <ref-features-machine>` of OpenEmbedded-Core
can be used.

.. index:: DISTRO_FEATURES

Distro Features
===============

CoreOS doesn't define any custom distro feature for now, but the 
:external:ref:`DISTRO_FEATURES <ref-features-distro>` of OpenEmbedded-Core
can be used.

.. index:: IMAGE_FEATURES

Image Features
==============

Some image features are available when you inherit the
:ref:`coreos-image <ref-classes-coreos-image>` class. The current list of
these features is as follows:

-  *hwcodecs:* Installs hardware acceleration codecs.
-  *tools-debug:* Installs debugging tools such as ``strace`` and ``gdb``.
-  *tools-profile:* Installs profiling tools such as ``valgrind`` and ``perf``.
-  *ssh-server:* Installs the Dropbear minimal SSH server.

:external:ref:`IMAGE_FEATURES <ref-features-image>` defined in OpenEmbedded-Core
are also available, but note that the
:ref:`coreos-image <ref-classes-coreos-image>` class don't inherit from the
:external:ref:`core-image <ref-classes-core-image>` class, thus `core-image`
specific features are not available.
