EDIT: Never mind! The old style “copy a fully-installed machine” method clearly has this problem. Sorry, it was Friday before a long weekend.
I am doing some further research on trying to solve the problem I mentioned in this thread: https://www.afp548.com/forum/viewtopic.php?forum=45&showtopic=26033
Because of the way I currently have things configured, I have 30+ machines with a local user (controlled with local MCX settings) that have the same GeneratedUID. (For background information: https://www.afp548.com/forum/viewtopic.php?forum=45&showtopic=23326.)
The question: is this problematic / not advisable / evil? Could it be causing the problems I describe in thread 26033?
