If you have multiple machines to update in your network, this may be ideal for you. It will allow you to use your HDA as a local Fedora/RPMFusion Updates repository (hereafter referred to as <strong><em>repo</em></strong>). This was developed on Fedora 12 platform.
Once the initial setup is complete, all repos will be updated nightly with any changes automatically. Then whenever you do an update to your HDA or Fedora clients, packages will be pulled from your HDA versus a Fedora mirror over the internet. I have built scripts to do all the steps below and will post them here soon.
