+various version of getfacl handle symlink differently
+# $ ln -s d l
+The result of "getfacl -dR . | grep file | sort" is related with
+the dentry item order in parent directory. Such order depends on
+FS implementation. Fix with -P (--physical) option.
+# $ getfacl -dR . | grep file | sort
+ $ getfacl -dRP . | grep file | sort
