Matt,

Great to know that at least one person (except me) thinks it is a viable
idea to make user able to deploy master node not depending on ISO.

AFAIK, both deb and rpm packages can run arbitrary scripts during
post-installation stage. And I remember when Ubuntu came out with their
Juju based openstack deployment scheme they used to rely totally on deb
post install scripts during deployment their Cobbler+Juju master node.
Besides, at least when you use deb packages it is possible to interact with
user using debconf dialog.

Anyway, Docker containers seem to be an appropriate solution for this use
case, at least in a short term perspective.
