[SunHELP] a question

I think you missed the grasp of my statement. There are more than two ways
to skin a cat. Sun recommends one partition and I know a lot of
knowledgeable folks who follow suit. I always liked one partition. That
does not imply that one does not know how. Dont make assumptions about
someone's knowledge until you know what you are talking about as well.
In life I find the best policy is to listen to other people's ideas without
making judgements.
Have a nice day.
