# ID: zfs_acl_tar_002_pos
#
# DESCRIPTION:
# Verify that '$TAR' command with -p@ option supports to archive ZFS ACLs 
#	& xattrs
#
# STRATEGY:
# 1. Create file and directory in zfs filesystem
# 2. Add new ACE in ACL of file and directory
# 3. Create xattr of the file and directory
# 4. Use $TAR cf@ to archive file and directory
# 5. Use $TAR xf@ to extract the archive file
# 6. Verify that the restored ACLs & xttrs of file and directory identify
#    with the origional ones. 
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-12-16)
