Another clarification: ifplugd depends on ifupdown and breaks with
ifupdown2. The
real culprit of the startup delay is ifupdown together with dhcp, and
it's not caused
by the time-out activation of the wired interface as you pointed out,
but rather by
the management ofany of the existent clauses for /etc/network/interfaces
with the
wrong version ofifupdown -better said-,  regardless whether is a wired
or wireless
device.

I do not mean to be categorical, I only speak from my personal
experiences :)

Aitor.
