We HAVE tried it. We found that your nd root at to be > 0. 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.
