  37 # DESCRIPTION:
  38 # Verify that a zvol device can be used as a swap device
  39 # through /etc/vfstab configuration.
  40 #
  41 # STRATEGY:
  42 # 1. Modify /etc/vfstab to add the test zvol as swap device.
  43 # 2. Use /sbin/swapadd to add zvol as swap device throuth /etc/vfstab
  44 # 3. Create a file under /tmp and verify the file
