# DESCRIPTION:
#	Project ID affects POSIX behavior
#
#
# STRATEGY:
#	1. Create three directories
#	2. Set tdir1 and tdir3 project ID as PRJID1,
#	   set tdir2 project ID as PRJID2.
#	3. Create regular file under tdir1. It inherits tdir1 project ID.
#	4. Hardlink from tdir1's child to tdir2 should be denied,
#	   move tdir1's child to tdir2 will be object recreated.
#	5. Hardlink from tdir1's child to tdir3 should succeed.
#
