current desktop spin

[Matthias Clasen <mclasen redhat com>]

Hey Jeremy, 

looking at a livecd spun today, I notice a number of issues:

1) rhgb is installed and on the kernel cmdline, but does not come up
2) didn't we decide to put nss-mdns on the livecd ? 
3) my iso ended up at 726M, something must have grown considerably in
the last few days
