Our rawhide compose process involves sshing as mock on releng1 to mock on the various builders. Last night this part of rawhide failed due to xenbuilder2 changing ssh keys. However today I couldn't duplicate the ssh to correct the key, and promptly got plonked into the deny-hosts file.

Turns out that xenbuilder2 doesn't have a 'mock' user unlike the other builders (like xenbuilder1) and thus sshing will fail. I'm not sure how the other builders were set up but we'll need to mimic them for now until we come up with a better way to get rawhide composed.
