hi hello again

I believe you are talking about this bp 
https://blueprints.launchpad.net/magnum/+spec/cache-docker-images
then ignore my previous reply, that may another topic to solve network 
limited problem.

I think you are on the right way to build docker images but this image 
could only bootstrap by cloud-init, without cloud-init
the container image tar file are not loaded at all, but seems this may 
not be the best way.

I'v suggest that may be the best way is we pull docker images while 
building atomic-image. Per my understanding, the
image build process is we mount the image to read/write mode to some tmp 
directory and chroot to to that dircetory,
we can do some custome operation there.

I can do a try on the build progress(guess rpm-ostree should support 
some hook scripts)
