sub domain for ddns - resolving

[Vernon A. Fort]

I have successfully configured an internal name server to allow for ddns 
for my dynamic ip address (dhcpd), both forward and reverse within 
separate files.  My initial intension was to keep the primary/static 
hosts within a manually editable file.  Unfortunately, I discovered you 
cannot push out a Search List to the workstations via dhcpd AFTER I got 
well into the setup.  I have googled and read several posts with similar 
issues but no conclusions.

DETAIL:
       primary domain:      mysite.int with "20.168.192.in-addr.arpa"
       secondary domain:   ddns.mysite.int with 
"20.168.192.ddns.in-addr.arpa"

  So, how does one have the ddns sub-domain assigned to the Workstation 
resolve hosts entries within the primary domain.  As I understand, named 
is NOT a resolver, it just returns answers to the query from the 
workstation?

  What I need is the workstation host (wkst01.ddns.mysite.int) to 
resolve serverone (serverone.mysite.int) without the FQDN.

      1.  Is there something I missed, similar to the $GENERATE 
statement for the in-addr.arpa
       2.  Run Dual name server, the sub-domain forwarding to the primary?

Or should I just scrap the sub-domain idea and just have everything 
within two zone files, using nsupdate to add/modify/remove?  I have 
already invested 12 hours, most of it reading.  I know this has been 
asked several times but I have not found any firm conclusion.  Some 
advise PLEASE!
