It is'nt that simple. Turn on swap *partitions* is one of the first things
you do at boot time. Usally before checking and mounting filesystems.
For swap *files* you have to wait until your filesystems are mounted.

Same for shutdown: Turn off swap files has to be done before umounting
filesystems, swap partitions can later.

I use this "two-step" swapon: Have a 40 MB swap partition, and after
mounting all the filesystems I run a script which searches the
DOS-Partitions for 386spart.par files :-) BTW: swap priorities are
handy for this: Of cource it is a good idea to run the swap file at
lower priority...

For the new swapon/off: Would be handy to have a "-t [ file | part ]"
