Do you want linux to raid 0 your swap for you? ime your script will use
just one disk for swap until it overflows before bringing the next into
use, etc etc.

If you want swap striped, I think you'll need to use "swapon -p=1" or
whatever number. Otherwise I think you'll find all your swaps are
assigned different priorities. Of course, that may be what you want,
depending on how your disks are laid out.
