-	  To compile this support as a module, choose M here: the module will be
-	  called autofs4.  You will need to add "alias autofs autofs4" to your
-	  modules configuration file.
+	  This module is in the process of being renamed from autofs4 to
+	  autofs. Since autofs is now the only module that provides the
+	  autofs file system the module is not version 4 specific.

+	  The autofs4 module is now built from the source located in
+	  fs/autofs. The autofs4 directory and its configuration entry
+	  will be removed two kernel versions from the inclusion of this
+	  change.
+
+	  Changes that will need to be made should be limited to:
+	  - source include statments should be changed from autofs_fs4.h to
+	    autofs_fs.h since these two header files have been merged.
+	  - user space scripts that manually load autofs4.ko should be
+	    changed to load autofs.ko. But since the module directory name
+	    and the module name are the same as the file system name there
+	    is no need to manually load module.
+	  - any "alias autofs autofs4" will need to be removed.
+
+	  Please configure AUTOFS_FS instead of AUTOFS4_FS from now on.
