This patch allows for an optional new layout for ipk feed directories which I've called a 'hierarchical feed' and is based on how Debian pools package files. It is disabled by default and is enabled by setting IPK_HIERARCHICAL_FEED to "1". In the traditional feed layout, package files are placed in <outdir>/<arch>/. This can lead to several thousand files existing in a single directory which is often a problem if developers want to upload a package feed to a shared web hosting provider. For example, in my case, listing files via FTP only shows the first 2000 files, breaking my scripts which attempt to upload only new and changed files via FTP. In the hierarchical feed, package files are written to <outdir>/<arch>/<pkg_prefix>/<pkg_subdir>, where pkg_prefix is the first letter of the package file name for non-lib packages or "lib" plus the 4th letter of the package file name for lib packages (eg, 'l' for less, 'libc' for libc6). pkg_subdir is the root of the package file name, discarding the version and architecture parts and the common suffixes '-dbg', '-dev', '-doc', '-staticdev', '-locale' and '-locale-*' which are listed in meta/conf/bitbake.conf. This change relies on recent patches to opkg-utils which support hierarchical package feeds.

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, patches against the various components should be sent to their respective upstreams.
bitbake: bitbake-devel@lists.openembedded.org
meta-yocto: poky@yoctoproject.org
Most 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. 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.
