Log:
  If dumpdev is AUTO but no dump device has been set -- i.e., there is no swap
  space configured for rc.d/dumpon to designate for dumping -- then exit
  silently rather than with a
  > realpath: /dev/dumpdev: No such file or directory
  error message.
  
  An argument could be made that we should print a (more informative) warning
  message; but given that under the same conditions the rc.d/dumpon script will
  already print a
  > No suitable dump device was found
  warning, it seems that printing an additional
  > Dump device does not exist.  Savecore not run.
  warning would be superfluous.
