# Each ifplugd instance handles only one interface, so this script is
|
|
# designed to be symlinked per interface. For each interface create a

# symlink with .IFACE appended to the name. E.g. to launch ifplugd for
|
|
# eth1 create a symlink from /etc/init.d/S41ifplugd.eth1 to this
|
|
# script. DEFAULT_IFACE sets the interface the non-symlink script will
|
|
# use, set it to empty in /etc/default/ifplugd to disable the default
|
|
# instance and use symlinked instances only.
