So, if I understand your post correctly, if I request a particular
option from the DHCP server and it provides that option, dhclient will
respect it. However, if I do not request a specific option and the
server sends it anyways, dhclient will ignore the fact that I did not
request it (based on the configuration) and use it anyways?
It makes no sense that dhclient would function that way. I was
actually going to say, "that sounds like a bug." However, I can't
convince myself that this isn't by design.
Oh well, a hook script it will have to be then.
