-# Modified April 9, 2004 by Leann Ogasawara <ogasawara@osdl.org>
-#  - expanded @tests array to add more symlinks and permissions tests
-#  - some of the symlinks tests also test lack of node creation
-#  - added symlink_test() function
-#  - moved permissions and major_minor tests into their own functions
