We are using fog 0.32 to image and deploy windows 8, and it works just fine. We use ‘multiple partition image single disk’ image type and select windows 7 as host os in the host settings.
We also run the fogprep.exe before imaging but don’t change anything to it, so I’m not actually sure it does anything. Also the hostname changer, joining AD and deploying snap-ins and printers from the fog server works out of the box.
The only thing we encountered problems with was that the fog service runs by default as a local system account and once the computer joined a domain, the fog service wasn’t able to install snap-ins anymore. Changing the fog service to run as a domain admin account after joining a domain solves this issue. I’m now trying to automate this with a script.
