The truth is out there!

This is what I did: Left-click on NM, select "manual config", add a
search domain, close. Result - resolv.conf has the new domain in it.
dhclient was not involved.

When I select an option in NetworkManager and it opens a dialogue called
"Network Settings", I reckon it's fair enough to call that "Network
Manager", but I take your point. Technically not NM.

I do know where it's saved (at least the search domains) - it is saved
in /etc/resolv.conf. Try it.

No, it was NOT dhclient. dhclient had not yet been triggered. This was
done solely within the "Network Settings" dialogue, without requesting a
reconnect. When dhclient *did* get triggered, then it did overwrite the
file, as you describe. I.e., both the "Network Settings" dialogue AND
dhclient will modify resolv.conf.

No argument there. You're quite right, and I said so a couple of emails
ago :-)
