This is a regression test for bugs in the nfsacl protocol extension.
The test should be run on an NFS export mount with ACL support.

	Create a test directory and file.

	$ umask 022
	$ mkdir -p test/sub
	$ echo blah > test/sub/blah

	$ cp -rp test/sub test/sub2
	$ find test/sub2 | sort | xargs ls -dl | awk '{print $1,$8}'
	> drwxr-xr-x test/sub2
	> -rw-r--r-- test/sub2/blah

	$ rm -rf test/sub2

	$ setfacl -m u:daemon:rwx test/sub
	$ setfacl -dm u:daemon:rwx test/sub
	$ getfattr -m- test/sub
	> # file: test/sub
	> system.posix_acl_access
	> system.posix_acl_default
	>

	$ cp -rp test/sub test/sub2
	$ find test/sub2 | sort | xargs ls -dl | awk '{print $1,$8}'
	> drwxrwxr-x+ test/sub2
	> -rw-r--r-- test/sub2/blah

	$ rm -rf test/sub2

	$ setfacl -m u:daemon:rw test/sub/blah
	$ cp -rp test/sub test/sub2
	$ find test/sub2 | sort | xargs ls -dl | awk '{print $1,$8}'
	> drwxrwxr-x+ test/sub2
	> -rw-rw-r--+ test/sub2/blah

	$ rm -rf test/sub2

	Clean up.

	$ rm -rf test
