True. But see below.

Well, it may be more semantics, but dhclient, apart from being the
*source* of (some of) the details, certainly has nothing to do with
storing them in any configuration files. NetworkManager, on the other
hand, does. It seems reasonable to say that it was NetworkManager
resetting the details I was seeing in its dialogue boxes.

So, just to be bloody-minded, I just went and added a domain to the
search list in the Network manager dialogue again. It had no effect
on /etc/network/interfaces at all.

BUT: The new search list *did* get written into /etc/resolv.conf! Which
means (just to confuse the issue totally) - that it dang well should
have worked when I did it the first time. At least until NetworkManager
renewed or rediscovered an address and overrode the details
in /etc/resolv.conf with those from the DHCP client. In fact, it makes
me wonder if I was too clever by half and DID tell NetworkManager to
reconnect after I made the change - maybe to see if the change would
