For the use that I wanted it is sufficient: code to park on a remote box that may be connected (manually) for occasional maintenance. If it's reasonable from other perspectives I think it would be good to reinclude the external command option in dhclient.conf. Otherwise monitoring the dhcp lease with the -L flag I had not thought of but does provide the necessary trigger to update dns. Thanks, Dhu -- Ne obliviscaris, vix ea nostra voco.
