Okay, sorry. I think that maybe it shouldn't be set in the default
dhclient.conf, or there should at least be a note about it in NEWS.Debian.
This is going to bite everyone who uses dhclient on a portable computer.

Also, what's going to happen if the DHCP server does send the hostname anyway?
I'm afraid that the hostname will be changed then, allowing a malicious DHCP
server to change hostnames of Debian machines whenever it likes to.
