KIWI plugin to prepare an image root tree for a cross architecture build process. Building an image for a different architecture than the host architecture can be done in several ways. One way is to emulate a virtual machine of the target architecture using the boxbuild command. However, that emulation is not very fast. A faster but also more complex approach is to provide binary emulation in userspace. This plugin prepares a new image target directory with all data needed to run applications for the image target architecture using the QEMU User Emulation feature.
