can dhclient be made to contact a specific dhcp server by IP say?

[Walter Tautz <wtautz@math.uwaterloo.ca>]

I'm trying to use systemimager on our network, alas the
network switches forward general dhcp broadcasts to a
server I have no control over. I'm trying to setup
a special server that systemimager can use or for that
matter FAI if I choose to use the sytem. At the moment
I'm trying to use systemimager.
