  So, if the disklabel says "swap" for partition x, specifying "auto"
will use it?  Am I reading that right?

   The release notes for the next release should have added a reminder to
check your disklabels before installing.  You can mount and use a partition
marked swap as a normal mounted filesystem.  It's unlikely that someone
would, as newfs complains if you try to create the filesystem in the first
place, but a warning wouldn't hurt.

  Maybe have a auto_swapconfig=YES that can be turned off to cause swap1 to
never to the auto config.

  A "-n" option, to see what would be done w/o doing it, would be nice.
