Tried that, didn't work.  
Got overwritten, anyway.

The /etc/resolv.conf.tail trick works, if all you need is a 'lookup
file bind' on the end of your file.

In my case, however, I wanted to NOT use my ISP's DNS servers, but
rather, my own in-house DNS server, and specify my own domain name. 
What I did to achieve this is change two lines of
/sbin/dhclient-script to rewrite /etc/resolv.conf.dhcp instead of
/etc/resolv.conf.  This way, I could see what my ISP was wanting to do
to me (that is sometimes useful to know), and yet what *I* put in
resolv.conf stayed.  

Nick.
