Jeremy,
It's what I could get running on City Network's generously provided infrastructure. I wasn't getting the same results installing there as locally, for instance had to turn off etcd but I don't have to on my local virtual box instance. I'd get partially through master and stein installs and then errors so I kind of stopped at a good installation and quickly made a 'golden' image and moved on to working on the workshop itself. I also attempted packstack and had errors as well so it just made more sense to move on vs continuously pestering Florian.:).
Note: Errors could definitely be a result of me trying to run as lean as possible and not take advantage of the resources being donated.
