If the same username exists on both target and the build host, but the uids differ, and we start target via NFS, then the uid for the user will be incorrect on target. For example, if postfix's uid on host is 119 and on target is 1024, then if we start target via NFS, the uid for postfix will be 119. The root cause is that when we use runqemu-extract-sdk to generate the NFS rootfs for later use, the tar command will respect the username instead of uid. So if PSEUDO_PASSWD environment is not set correctly, the host /etc/passwd will be used, resulting in wrong uids. The situation for gid is completely analogous to that of uid. It's almost impossible for the runqemu-extract-sdk to guess the correct location of the needed password file merely based on the target tarball name. This patch solves this problem by adding the '--numeric-owner' option to the tar command so that the uid/gid will be used when extracting the tarball using runqemu-extract-sdk. In this situation, we'll always get the correct uid/gid after extracting the tarball.

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.
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.
