I strongly recommend that you try upgrading with 'fedup' next time around. It's far-and-away better than our historical upgrade processes and works in-place. I've personally gone from F17->F18->F19 using it with no ill effects.
I had a lot of problems with fedup from 17 to 18. They were fixable after you figured out the issues, but, it caused problems on two systems anyway. Apart from that, the update problem has been pretty tame. Things have been sufficiently stable that I no longer update with a full new install in its own partition while retaining the original so that I can backtrack. I probably should, but I don't.
I considered some of the answers insightful, for example: "We know money doesn't create loyalty--a sense of purpose does".
Yes, some answers lacked deep content in that they were the expected carefully worded answer. Unfortunately, these questions almost required such an answer. For example, "Why do we still confer most-favored nation trading status onto a Nation who is actively engaged in efforts to spy on and attack our government and corporate computer systems?" Although this is a very good question, General Lord seems like the wrong person to even attempt that question. The probable complaint is that the answers lacked detail. For example, from the same question "What, if anything, is being done against this type of cyber-terrorism against us and our allies?" The answer lacks detail, but it would be difficult to add detail to his answer without discussing a specific threat. I would have enjoyed that discussion, BTW, and use his answer as a start: "working to improve our ability to respond to cyber attacks, reduce the potential damage from such events, and to reduce our vulnerability to such attacks."
Thank you General Lord for your time!
