Decoupling the image creation from how the image is used is a key goal, especially since organizations often want to separate environment preparation and development along role lines.

Windows images are special, yes. For those, perhaps chat with the Murano
folk?

Containers will work fine in diskimage-builder. One only needs to hack
in the ability to save in the container image format rather than qcow2.

I actually think diskimage-builder would be really useful for container
building, as it doesn't make any assumptions about things like having a
kernel. In fact we've discussed the possibility of using lxc to do the
image builds instead of chroot so that the builds would be more
isolated from the build host.
