Reuses the mic/livecd infrastructure but heavily subclasses and modifies it to adapt to the special needs of building images from existing OpenEmbedded build artifacts. In addition to the OE-specific mic objects and modifications to the underlying infrastructure, this adds a mechanism to allow OE kickstart files to be 'canned' and made available to users via the 'wic list images' command. Two initial OE kickstart files have been added as canned .wks files: directdisk, which implements the same thing as the images created by directdisk.bbclass, and mkefidisk, which can essentially be used as a replacement for mkefidisk.sh. Of course, since creation of these images are now driven by .wks files rather than being hard-coded into class files or scripts, they can be easily modified to generate different variations on those images. They also don't require root priveleges, since they don't use mount to create the images. They don't however write to media like mkefidisk.sh does, but rather create images that can be written onto media.
