Check out the manpage for mount_swapfs.  Apparently swapfile.front isn't 
a separate file--it's just a frontend for optimized access to swapfile.
Unfortunately, the documentation on this point is not very complete.
I would appreciate hearing from anyone who really knows the details;
for example, I want to know just where in the boot process mount_swapfs
gets invoked, and what the best way is to put the swapfile onto another
disk.
