dhccra and dhclient from branch built, but...

[Dave Taht]

Regrettably I just destroyed the lab almost completely in alistair's
rush out the door, and need to re-organize, retask, and reflash some
hardware before being able to continue.

I hope you have copies of the scripts that were living on the sd-cpe2
box. I have setup4, setup6, and the relevant dhclient script from last
night.

Well this affects wireless interfaces. They come and go every time the
network is reset.

I did a cvs up from the branch. I am puzzled as to what the -l option
was supposed to be doing in the first place.

 "Usage: dhccra [-d] [-q] [-L] [-c <hops>] [-p <port>]\n" \
