Regarding building distro rpms or debs with raisin that was never the 
scope of it. Raisin intends to be a quick method of building xen + a set 
of tools related to it, primarily for development purposes 
(https://wiki.xenproject.org/wiki/Raisin and 
https://blog.xenproject.org/2015/06/28/project-raisin-raise-xen/)
