During the Paris session someone specifically mentioned they didn't want to
use fpm, and wanted plain spec files instead. If that person is on this
list, or if there's anyone else in that position, care to elaborate? Is
there a specific limitation people are concerned about?

I asked you about this in Paris, but for the benefit of the list, what
about native packages? I find I need to package things like libvirt as
well. As a community are we expecting to run one packaging tool for
Openstack's python packages and one tool for everything else, or do we
expect that to be combined into a single tool that can handle both?
