Sorry, I wasn't clear.  I should not write late at night (repeat 100 times).  
I already had one swap file (/usr4/swapfile) but this was insufficient.  So 
I created another (/usr2/swapfile).  My problem was trying to figure out 
how to specify both swapfiles withint the same /etc/vntab file.

Now that is interesting.  Thanks.

For the time being, I've changed /etc/vntab to refer to the new swap file 
instead of the old swap file.  I'll clean things up after BSDCon.

Thanks.
