Opkg is a lightweight package management system. It is written in C and resembles apt/dpkg in operation. It is intended for use on embedded Linux devices and is used in this capacity in the OpenEmbedded and OpenWrt projects, as well as the Yocto Project.
As best it can, opkg maintains backwards compatibility with ipkg and conforms to a subset of debian's policy manual regarding control files.

Build Appliance

NOTE: Hob is now deprecated and will no longer be available beginning with the 2.1 release of the Yocto Project. You can use Toaster instead. Hob will still be available inside the Build Appliance, but might not work as expected, since it is no longer maintained.


Poky is a reference system of the Yocto Project. It contains the OpenEmbedded Build System (BitBake and OpenEmbedded Core) as well as a set of metadata to get you started building your own distro. To use the Yocto Project tools, you can download Poky and use it to bootstrap your own distribution.
