There is a major issue with opkg images at the moment as preinst functions are not being executed before their dependencies are installed and this is leading to corruption of images containing avahi/dbus in particular. There are various changes in upstream opkg in the last 8 revisions which make changes in this area but sadly these aren't enough to get things working for us. I've updated to the latest svn revision with this patch since it makes sense to pull in those changes first and then supplement them with the attached patches. There is a full description of the patches in the patch headers but in summary they: a) Ensure preinst functions execute with their dependencies installed. This is a pretty invasive change as it changes the package install ordering in general. b) Ensure opkg sets $D, not $PKG_ROOT which we don't use c) Change opkg to allow execution of postinstall functions which fail resulting in execution on the target device as rootfs_ipk.bbclass currently does manually. The remaining changes interface this with the rest of the OE build infrastructure, adding in the option to tell opkg to run the preinst and postinst functions, ensure the correct environment is present for the postinst scripts and removing the now unneeded rootfs_ipk class code which opkg now does itself.

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:
