I can still reproduce this bug (over 3 years old by now!) with
isc-dhcp-client 4.2.2.dfsg.1-5+deb70u2 (currently in testing):

$ cat /etc/resolv.conf
domain gesteb.lan
search gesteb.lan
$ cat >>/etc/dhcp/dhclient.conf <<EOF
supersede domain-name "gesteb-service.de";
prepend domain-search "gesteb-service.de";
$ ifdown eth0 && ifup eth0
$ cat /etc/resolv.conf .
domain gesteb-service.de
search gesteb-service.de.

Is there any news from ISC about this issue (tracked as [ISC-Bugs
