Hostname for DNS dynamic updates

[Ashley M. Kirchner]

    Is there a way to specify what the FQDN should be (or at least the 
hostname) when a client requests to update it's own A record?  Right now 
they're coming in with whatever the client has as hostname, which 
sometimes can be some random string set when the machine was first built 
(think Dell.)  What I'd like is for the A (and PTR) record to use the 
hostname I specified in dhcpd.conf.  For example, I have this in my 
dhcpd.conf file:

    host patrick { hardware ethernet 11:22:33:44:55:66; }

    And when the PTR and A records get updated, I get this:

    PTR record:
       100                     PTR     D9H3BH71.pcraft.com.

    A Record:
       D9H3BH71                A       192.168.1.100


    I want it to say 'patrick' instead of that 'D9H3BH71' string that 
the client sends.
