Hello, we have been bitten by something that obvoiusly is a feature, not a bug, but I do not quite understand the intentions and reasoning behind it. I have a host with manual interface and resolver configuration and an additional interface that should get it's IP address via DHCP. But only it's IP address and netmask, nothing else. The DHCP server used hands out only IP addresses/netmasks, no domain-name-servers, domain-name, etc. configured. Yet, if there happens to exist a /etc/resolv.conf.sav file, every renewal of the lease by dhclient overwrites the contents of /etc/resolv.conf with those of resolv.conf.sav. In my particular case the .sav file contained an internal nameserver that was used when I initially set up the host in the lab. This entry was of no use to the server after it had been deployed in our datacenter. Can anyone shed some light on the intended mechanism? Studying the dhclient-script was not too helpful, either.
