It's not a security issue if you're on a single user desktop/laptop, and
therefore something that could be configured up during installation. One
idea I had was to suggest having install "profiles" available - I'd love
to have an anaconda option I can click that will:

* Add me to sudoers automatically (first thing I do on every Fedora/RHEL
system, and the most annoying thing missing from a standard install)
* Add me to various groups useful to desktop self-admin, etc.
* (Disable SELinux policy with a vengeance :P)

That's not true. You already have PolicyKit support and even look to see
if you have a policy. So that authorization could just be setup in
advance for pulseaudio if it's running on a desktop system.
