Hi scanner,

You can use a vnode disk for swapping.

Here is an example for vn-swap (64Mb)

1. Put in your kernel configfile a line "pseudo-device   vn"
   and  recompile your kernel.
2. cd /dev; sh ./MAKEDEV vn0
3. dd if=/dev/zero of=/usr/swap0 bs=1024k count=64

4. vnconfig -ce /dev/vn0c /usr/swap0 swap

You can put step 4 into your /etc/rc.local to enable it on boottime.
