You're right. I misread /sbin/dhclient-script.

NetworkManager doesn't manage resolv.conf at all.

When it runs, dhclient will write /etc/resolv.conf based on information
received from the DHCP server and any additional information found in
the DHCP client configuration file.

If you want to change what dhclient does when it runs, you can make
changes in the configuration file /etc/dhcp3/dhclient.conf and/or to the
script /sbin/dhclient-script. In general, the config file describes how
the client should interact with the server and what adjustments (if any)
should be made to the information retrieved. The script defines what to
do after the information is retrieved - such as setting up interfaces
and writing nameserver information into /etc/resolv.conf.

The Network Settings tool (System -> Administration -> Network) reads
and lets you modify /etc/resolv.conf directly; however, any mods you
make will be wiped the next time dhclient runs. The Network Settings
tool also reads and lets you modify the /etc/hosts
and /etc/network/interfaces files directly. This tool is what runs when
you select "manual configuration" inside Network Manager.

Derek, thanks for your patience. It helped me learn a lot.

Regards, K.
