  40 # DESCRIPTION:
  41 # ZFS will not interfere with devices that are in use by ufsdump or
  42 # ufsrestore.
  43 #
  44 # STRATEGY:
  45 # 1. newfs a disk
  46 # 2. mount the disk
  47 # 3. create files and dirs on disk
  48 # 4. umount the disk
  49 # 5. ufsdump this disk to a backup disk
  50 # 6. Try to create a ZFS pool with same disk (also as a spare device)
  51 # 7. ufsrestore the disk from backup
  52 # 8. try to create a zpool during the ufsrestore
  53 #
