+#	rc file for automount using a Sun-style "master map".
+#	We first look for a local /etc/auto.master, then a YP
+#	map with that name

+#	On most distributions, this file should be called:
+#	/etc/rc.d/init.d/autofs or /etc/init.d/autofs
+#
+
+#       This is used in the Debian distribution to determine the proper
+#       location for the S- and K-links to this init file.
+#	The following value is extracted by debstd to figure out how to
+#	generate the postinst script. Edit the field to change the way the
+#	script is registered through update-rc.d (see the manpage for
+#	update-rc.d!)
