Yes. You first use "dd if=/dev/zero ..." to create a file of
sufficient size somewhere, then use vnconfig to enable swapping
on it. Please refer to "man vnconfig" for all the details.
Note that you must have "pseudo-device vn" in your kernel (see
LINT). Also note that you cannot disable swapping on a file,
once you have enabled it (except by rebooting, of course).
