# DESCRIPTION:
#
# Creating files on ufs and tmpfs, and copying those files to ZFS with
# appropriate cp flags, the xattrs will still be readable.
#
# STRATEGY:
#	1. Create files in ufs and tmpfs 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 filesystem.
