The incremental rpm generation usually broke when package_rpm.bbclass
changed, change its implementation to make it more stable:
* It depended on the previous and current saved manifest files in
the past, it would break when the manifest changed. Now query the
previous and current installed pkgs from rootfs/var/lib and
rootfs/install/, this would be more reliable, the manifest's change
would not affect it any more.
* Add explanations before package_install_internal_rpm to explain what
does the function do.
* Remove an unwanted "awk '{print $1}'".

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 = "") and contains only emulated machine support.
