-config AUTOFS_FS
-	tristate "Kernel automounter support"
-	depends on BKL # unfixable, just use autofs4
-	help
-	  The automounter is a tool to automatically mount remote file systems
-	  on demand. This implementation is partially kernel-based to reduce
-	  overhead in the already-mounted case; this is unlike the BSD
-	  automounter (amd), which is a pure user space daemon.
-
-	  To use the automounter you need the user-space tools from the autofs
-	  package; you can find the location in <file:Documentation/Changes>.
-	  You also want to answer Y to "NFS file system support", below.
-
-	  If you want to use the newer version of the automounter with more
-	  features, say N here and say Y to "Kernel automounter v4 support",
-	  below.
-
-	  To compile this support as a module, choose M here: the module will be
-	  called autofs.
-
-	  If you are not a part of a fairly large, distributed network, you
-	  probably do not need an automounter, and can say N here.
