It appears that, at least on my 2006.1 Gentoo distro, possibly with iproute2 I
am not positive if it extends beyond Gentoo, that someone decided to
automatically load the arping module even when not asked for. This causes the
2 second delay. A fix for Gentoo installs is after your modules=("iproute2")
an additional line of modules=("!arping") cures the problem. I have no idea
why they feel this is required on all networking code since they load it no
matter what, but unless it does something specifically important to our use,
it seems to only get in the way. We use 100% static
assignments,gateways,routes,everything so we need no automatic detections of
anything at all, and in fact this also cured another of my problems where a
specific static route did not work, but now it does after killing that
module. I guess it made its own decisions that my instructions were not
worthy enough to obey. I am highly irked at Gentoo right now that they would
do this with no warnings or notifications that this was a new
automagic 'feature' which , unless i am made to understand why I need it,
simply has caused me problems.
