# DESCRIPTION:
# ZFS will not interfere with devices that are in use by ufsdump or
# ufsrestore.
#
# STRATEGY:
# 1. newfs a disk
# 2. mount the disk
# 3. create files and dirs on disk
# 4. umount the disk
# 5. ufsdump this disk to a backup disk
# 6. Try to create a ZFS pool with same disk (also as a spare device)
# 7. ufsrestore the disk from backup
# 8. try to create a zpool during the ufsrestore
#

# is to find the rest of the them and deal with them individually.
