I'm fairly certain that if dhclient does complain, it's not fatal,
because I rarely have one of cardbus tlp0 cards plugged into my
laptop when dhclient starts, and dhclient works ok.  

I also understand the goal to *not* touch an interface, and again, I'm
fairly certain that this method will prevent that, because I got sick
of waiting for strip0 (or something like that) being dhclient-ed on a
GENERIC_LAPTOP kernel, and this method prevented that.

In any case, the best way to see if this method works for you is to
try it ;-)
