+ 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
+ <https://www.kernel.org/pub/linux/daemons/autofs/>; you also want
+ to answer Y to "NFS file system 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 or
+ don't have a laptop which needs to dynamically reconfigure to the
+ local network, you probably do not need an automounter, and can say
+ N here.

Please configure AUTOFS_FS instead of AUTOFS4_FS from now on.
