Hi Paul, This is simply a proof of concept / test. If it works out and these test systems work, then we'll move on to production and talk to vendors.

Part of your upgrade migration and problem mitigation policy should be to get the suits who's sumptuous salaries are paid for with my taxes to coin up and buy support from either Red Hat or Ubuntu. Fact is any production system should have vendor support, in other words it should not be on your shoulders alone to figure this obscure stuff out. Anyway, the fact that Stan is once again "the man" (sorry Brinkerhof btw thanks for the workstations! :^) in finding a painless way out under Ubuntu is both interesting commendable. Anyway, that is how a bitter old man sees this situation.
