# DESCRIPTION:
# 'zpool create' will fail with ordinary file in swap
#
# STRATEGY:
# 1. Create a regular file on top of UFS-zvol filesystem
# 2. Try to create a new pool with regular file in swap
# 3. Verify the creation is failed.
#
# OSX STRATEGY:
# 1. Create a file in the current OSX swap file directory
# 2. Try to create a pool in that file
# 3. Verify the creation failed
