Code review comment for lp://qastaging/~doanac/charms/precise/ubuntu-ci-services-itself/lander-image-builder-start

I'm not too familiar with what lander_merge_parameters does, but if this is just supposed to be some sane values that should work as a quick test, that seems fine to me. Does it need to wait and see the end status for it? Does it need to do cleanup or anything? Every time you run this, you'll get a new copy of the image out in glance. I ask, because at least my personal account seems to have some limitations on the space, I got an error today that it was out of space.
