Well, i guess it's intended.
In /sbin/dhclient-script (or /etc/....):

RESOLV=/etc/resolv.conf

make_resolv_conf() {
        if [ \( ! -z "$new_domain_name" \) -a \
	     \( ! -z "$new_domain_name_servers" \) ]; then
	     echo search $new_domain_name > $RESOLV
	     for nameserver in $new_domain_name_servers; do
		     echo nameserver $nameserver
	     done >> $RESOLV
        fi
}
