I'll do real review later, but fow now I can answer the one easy question...
This patch adds the realm command to anaconda. It depends on the pykickstart changes I added earlier (hmmm, how should I reflect this dependency?).
We do this by changing this line in anaconda.spec.in:
%define pykickstartver 1.99.22
Of course, you don't know what version's going to be required yet and neither do I since this is bound for F19. We'll just have to make sure to remember to change this at merge time.
