@degaro While this response may be a bit snarky; my response would be, what would you have learned if it worked perfectly right out of the box? What do you now know that you didn’t just a few hours ago? You DO learn more and remember it longer when you have failures than success.
The FOG developers can only protect the IT admin so much. I agree that the question needs to be worded better. Maybe something like:

Would you like to have the FOG server act as the DHCP server for your network? [y/N] Y

The default is no, but the IT admin can still pick yes. The developers really can’t stop that.
