No problem from my perspective. It's interesting to hear about.

I'd love to use containers in Koji, but I think docker is still 
effectively x86-only (which is a shame, since I think the underlying 
kernel features are not). Plus there are a number of docker-isms that 
might make integration... tricky.

Also, a typical koji instance generates different chroot environments 
all the time, so I'm not sure how much IO we'd be able to save.

In any case, it's good to see work on this.
