# DESCRIPTION:
#
# Basic applications work with xattrs: cpio cp find mv pax tar
#
# STRATEGY:
#	1. For each application
#       2. Create an xattr and archive/move/copy/find files with xattr support
#	3. Also check that when appropriate flag is not used, the xattr
#	   doesn't get copied
#

# test scenarios below.

# For the archive applications below (tar, cpio, pax)
# we create two archives, one with xattrs, one without
# and try various cpio options extracting the archives
# with and without xattr support, checking for correct behaviour
