VARIABLES
       The  following  is  a list of variables that can be put in the configuration file, with an
       example in parentheses.  * marks the default.  For the meaning of suffix, see the  section
       Multiple addresses.

       STARTMODE {manual*|auto|hotplug|ifplugd|nfsroot|off}
              Choose when the interface should be set up.
              manual Interface  will be set up if ifup is called manually (without option boot or
                     hotplug)
              auto   Interface will be set up as soon as it is available (and service network was
                     started).  This  either happens at boot time when network is starting or via
                     hotplug when a interface is added to the system (by adding a device or load-
                     ing  a driver). To be backward compliant onboot, on and boot are aliases for
                     auto.
              hotplug
                     This mode is nearly the same as auto.  The difference between auto and  hot-
                     plug is that the latter does not make rcnetwork fail if the interface cannot
                     be brought up.
              ifplugd
                     The interface will be controlled from ifplugd. At initial ifup only  ifplugd
                     will  be started for this interface. Then if ifplugd detects a link if calls
                     ifup  again  which  finally  sets  the  interface  up.  See  also   variable
                     IFPLUGD_PRIORITY below.
              nfsroot
                     Nearly like auto, but interfaces with this startmode will never be shut down
                     via rcnetwork stop.  ifdown <interface> still works. Use this when you use a
                     root filesystem via network.
              off    Will never be activated.
