Here's my .conf file:
retry 60;
select-timeout 5;
initial-interval 2;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, host-name;
require subnet-mask, domain-name-servers;
This worked fine with older versions of the client.. it wasn't until I tried to
use the built in dhclient in /sbin that things broke. The real "bug" in this
PR is the change to tables.c.

Great.. I'm not a DHCP genius, I just copied over all the hostname parts from
the script we ran with the older client/server port that was installed over a
year ago on a 2.2.7 server, so if that will work better, than by all means,
commit that sequence for setting hostnames than what I have. Thanks.
