I used to really like ifplugd. mostly for the audible beep when things
are disconnected as it's easier to diagnose from afar.
being able to up/down interfaces based on connection state was also
great for dynamic routing when combined with openrc/netifrc
however, lack of clear config, no way to at runtime remove it from an
interface and just complete confusion over software based interfaces
i.e. gre tunnels or even macvlans.... all mean it is slowly being
removed from my boxen.
