Just now ($OpenBSD: dhclient-script,v 1.6 2004/05/06 18:22:41 claudio Exp $,
$FreeBSD: src/sbin/dhclient/dhclient-script,v 1.17.2.2 2008/04/11 00:17:59
brooks Exp $), dhclient-script invokes /etc/dhclient-exit-hooks:
-----
# Must be used on exit.   Invokes the local dhcp client exit hooks, if any.
exit_with_hooks() {
        exit_status=$1
        if [ -f /etc/dhclient-exit-hooks ]; then
                . /etc/dhclient-exit-hooks
        fi
        # probably should do something with exit status of the local script
        exit $exit_status
}
-----
I refrained from using the exit hooks, because dhclient-script needs
modifications in my patch: it duplicates the functionality of
/etc/rc.d/resolv.

Thanks for the suggestions!
