  36 # DESCRIPTION:
  37 # ZFS will not interfere with devices that are in use by ufsdump or
  38 # ufsrestore.
  39 #
  40 # STRATEGY:
  41 # 1. newfs a disk
  42 # 2. mount the disk
  43 # 3. create files and dirs on disk
  44 # 4. umount the disk
  45 # 5. ufsdump this disk to a backup disk
  46 # 6. Try to create a ZFS pool with same disk (also as a spare device)
  47 # 7. ufsrestore the disk from backup
  48 # 8. try to create a zpool during the ufsrestore
  49 #
