Then swap on both nd and your local disk. I have not tried this. (By the time I got my answer back from the Software Hotline I had already loaded my disk with a root and /usr also.

I believe that3 3 Mb was the magic number. I would be interested in knowing if someone has made this work with less. I would also like to know how the swap actually works when you have 2 swap devices and the first one is very small and the 2nd much larger. Does the systems use 1 MB of the first and then 1 mb of the second, etc. until the first 1 is full? Then does it use the 2nd swap device exclusively or does it continue to check the first device? I am working under the assumption that the system is interleaving the swap in 1 mb pages.
