TIME CONSUMING, then you don't want the cache to be blown away ESPECIALLY if there is a crash because if you HAVE to have updates to fix previous problems, then this can make it very difficult and time consuming to do updates especially for a beginner or any installer for first time installs followed by an upgrade. I would *think* that we should make it easier for these folks so that installation wont be as painful. For EXPERTS who do this for a living, THEY can set all the parameters to change the default behavior because THEY would KNOW the INSIDES AND OUT of these parameters whereas the beginner would have NO CLUE what is going on and gets pissed of by the minute. That is why I had to go get a beer to calm down since I was ranting from rabies as one poster jokingly stated. WOOF! :-) Dan
