Add a new function that is responsible for fixing directory and file permissions, owners and groups during the packaging process. This will fix various issues where two packages may create the same directory and end up with different permissions, owner and/or group. The issue being resolved is that if two packages conflict in their ownership of a directory, the first installed into the rootfs sets the permissions. This leads to a least potentially non-deterministic filesystems, at worst security defects. The user can specify their own settings via the configuration files specified in FILESYSTEM_PERMS_TABLES. If this is not defined, it will fall back to loading files/fs-perms.txt from BBPATH. The format of this file is documented within the file. By default all of the system directories, specified in bitbake.conf, will be fixed to be 0755, root, root. The fs-perms.txt contains a few default entries to correct documentation, locale, headers and debug sources. It was discovered these are often incorrect due to being directly copied from the build user environment. The entries needed to match the base-files package have also been added. Also tweak a couple of warnings to provide more diagnostic information.

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/community/documentation
