Well I have Debian installed -- turned out I was using the wrong server to grab packages from. I was relying on the defaults presented by the install, but for 3.0 you need to override these (at the moment anyway).
So it's all installed, just need to get on and configure various services and devices. Haven't touched it for a few days because I was away.
I hacked up a Javascript application today -- the FOAF-a-matic to generate FOAF descriptions automatically. Don't know what FOAF is? It stands for "Friend of a Friend" and is a way to describe yourself in RDF. Edd Dumbill's "XML Watch: Finding friends with XML and RDF" is a good starting point.
