Is this a problem? How much disk space is saved If I have to go create a
local mirror via fuel-createmirror?

Reliance on internet connectivity has been an issue since 6.1. For many
large users, complete access to the internet is not available or not
desired. If we want to continue down this path, we need to improve the
tools to setup the local mirror and properly document what urls/ports/etc
need to be available for the installation of openstack and any mirror
creation process. The ideal thing is to have an all-in-one CD similar to a
live cd that allows a user to completely try out fuel wherever they want
with out further requirements of internet access. If we don't want to
continue with that, we need to do a better job around providing the tools
for a user to get up and running in a timely fashion. Perhaps providing an
net-only iso and an all-included iso would be a better solution so people
will have their expectations properly set up front?
