+# You will need to set the dependencies in the netmount script to match

+# this file by following the examples below, and not by changing the
+# service script itself.
+#
+# Each of these examples is meant to be used separately. So, for
+# example, do not set rc_need to something like "net.eth0 dhcpcd".
+#
+# If you are using newnet and configuring your interfaces with static
+# addresses with the network script, you  should use this setting.

+# If you are using oldnet, you must list the specific net.* services you

+# This example assumes all of your netmounts can be reached on
+# eth0.

+# This example assumes some of your netmounts are on eth1 and some

+# If you are using a dynamic network management tool like

+# manage the network interfaces with the routes to your netmounts, you
