Robert - are you interested in working on the package autobuild for
RHEL & rebuilds?

I figure we have the Fedora expertise already. Anyone know enough to
get the Debian/Ubuntu packages building? (Maybe even automate
populating an Ubuntu PPA?) Same questions for OpenSUSE.

We have a classic chicken-and-egg problem with being of interest to
the OpenSUSE. Debian, Ubuntu, etc. communities - we need builds to
generate the interest of people who would want to maintain the
packages in their downstream distro repo.

Let's keep iterating on the content on http://ovirt.org/wiki/Jenkins,
not just the service minimums, but cleaning the setup steps, etc.
