Since the rewrite of the image construction code in python a few releases ago, we remove a couple of packages from the image as one of the final steps when constructing the image (notably update-rc.d and run-postinsts). However, because of the order of operations, these packages are still listed both in the buildhistory installed_package*.txt files and in the manifest file created next to the image, which is wrong. There were two possible solutions to this: (1) change the order such that the uninstallation occurs before calling ROOTFS_POSTPROCESS_COMMAND or (2) add another hook variable in such that we can have the package list collection code run at the right time. Because it's currently possible (but very much not recommended) to install additional packages within ROOTFS_POSTPROCESS_COMMAND, which may have postinstall scripts and thus require the packages we would otherwise uninstall if we were to take option 1, option 2 is really the least likely to cause problems. Therefore, add ROOTFS_POSTUNINSTALL_COMMAND and make the image and buildhistory classes use it. Fixes [YOCTO #6479].

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:

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.
