# DESCRIPTION:
#
# Create files on ufs|ext, copy those files to ZFS with appropriate cp flags,
# and verify the xattrs will still be readable.
#
# STRATEGY:
#	1. Create files in ufs|ext with xattrs
#	2. Copy those files to zfs
#	3. Ensure the xattrs can be read and written
#	4. Do the same in reverse.
#

# we need to be able to create zvols to hold our test ufs|ext filesystem.
