Interesting, I compiled it using Gentoo but will be installing it in to
an initrd image. I want to write a very simple dhclient-script and use
the dhclient.conf to request a few extra options. We have a custom
Linux OS that we need to configure during a PXE build. udhcpc is pretty
much designed for this, is this doable with dhclient? I have yet to see
a "simple" dhclient-script.
Thanks,
Jolynn

What OS?
On FreeBSD for example the client uses BPF, and installs a filter so
only DHCP packets arrive.
Most other OS have a similar but different mechanism.
