[Opendnssec-develop] getting information from the system

[Jakob Schlyter]

I see a couple possible problems here that we need to sort out before  
going any further.

- What we are talking about here is semi-automatic key rollovers, so  
things like generating and pre-publishing a key (where applicable) is  
done automatically?
- Do we also want to support manual key rollovers and key management?  
(and if so, why?)
