Make the following improvements to the SDK update process: * Use a manifest file with sha256sums to track files other than sstate and metadata that we need to update - e.g. conf files. This allows us to handle where files such as auto.conf may or may not be present, as well as the configuration changing without affecting task signatures - we still want the config files copied in that case rather than it saying nothing needs to be done. * Write the SSTATE_MIRRORS_append to site.conf rather than local.conf so that local.conf remains static (since we don't want to trigger an update every time). Also, If there is an SSTATE_MIRRORS value already set in the configuration we can skip this and assume it contains the needed packages. * Allow the update process to be run in any directory, don't assume we're already at the base of the SDK * Where practical, fetch remote files into a temporary location and then move them to the desired location at the end, to avoid a failed update leaving the SDK in a broken state. * Update all installed do_populate_sysroot / do_packagedata tasks instead of using the SDK targets. This ensures any item installed through dependencies after installation (e.g. when running "devtool build") won't go stale.

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-yocto(-bsp): Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
