Of course, now this begs the question: Is it possible to create a large file w/o actually writing that much to the device (ie uninitialized). There's absolutely no reason that a swap file needs to be fully initialized, only part which mkswap does. Of course, I would expect that ONLY root beable to do this. (or capsysadmin or whatever the caps are)
