Thanks! This is useful information, and does provide enough functionality
to solve my problem. Two problems with the auto-rewrite of resolv.conf by
dhclient-script still exist that make me want more configurability, though:

1) It prevents using any options in resolv.conf other than "search" and
"nameservers" (since that's all that is written in dhclient-script, and
anything else existing is erased). Granted, the only other options are
"sortlist" and "options", neither of which I have any use for, but somebody
else might.

2) It creates a small window of time when resolv.conf contains only partial
information, which could result in random failure of some process.

Anyway, I just don't like the idea of constantly rewriting a configuration
file if it isn't even changing. I still think there should be a way to turn
this off.

dhclient works just the way I would want it for a portable machine. The
machine in question here isn't portable, though. It's a gateway plugged
into a cablemodem on one side, and my home network on the other side. All I
want from the ISP is my IP address. Anyway, now I know how to setup
something that works, so all that remains is philosophical (or theoretical
at most).
