Artur, Thanks,
Upgrade code based on release of obsd is easy, but it would a big job to maintain early released of products based on previous version of obsd. For example, we would maintain 8 version of products from 3.3 to 4.0 if codes are upgraded every half years. Kevin you would need to maintain released boxes based on early version of obsd The thing is to upgrade released products based on > > > > Should we just isolate one by one manually as safety > approach?
