Okay:
to be paged. If the keyword ``swap'' is used instead of a special file
name, default configuration parameters will be used. (This option is
useful when trying to use mount_mfs on a machine without any disks.)
Now, it looks like "default configuration parameters" really means "it does
something safe, but too complicated for me to spell out here in a sentence."
I would hope that it simply means the primary swap area will be used (and
this might be totally in memory and not correspond to any disk partition).

Don't get me started about the value of man pages cross-referenced to an
HTML-ized archive of the source code.
Actually I was after the "reasonable" setting for how much of the swap area
it uses, if you don't hardwire the sector count with -s.
