There is no means of enabling or disabling the ifplugd service that I have 
found, because there is no /etc/init.d/ifplugd script.  Once installed ifplugd 
always starts at boot and daemonizes, configuring or tearing down connections 
as a link is detected or lost.

To make it clearer, this is how it used to work on two laptops:

I install ifplugd and remove from rc-update any net.<iface> that I have 
configured.  ifplugd will always start at boot as a daemon and will bring up 
and configure the wired NIC once a cable is detected.  There is no start up 
script in /etc/init.d/ installed by default, although the man page mentions 
it, along with /etc/ifplugd/ifplugd.conf, which is also not installed.  This 
is the only file that installed on my systems:

# find /etc -iname *ifplug*
/etc/ifplugd
/etc/ifplugd/ifplugd.action


I started this thread because recently I have to start my wired interface 
manually, after which point ipfplugd also starts, daemonizes and manages the 
connection.  This is not how it used to work - I never had to start the wired 
interface myself.

Furthermore, starting ifplugd on a terminal now shows that it is listening on 
eth0 instead of enp11s0, but hadn't tried this before things broke.  According 
to the man page eth0 is the default, but I can't recall manually specifying a 
different interface for ifplugd in the past.  It always brought up the wired 
interface, no matter what it was called.
