a DHCP reservation is when you convert a lease to a static reservation, 
so each time that MAC/identifier asks for an IP, you give it one thats 
preconfigured.   typically you can just cut/paste an entry form 
/var/state/dhcpd.leases into /etc/dhcpd.conf and tweak it to something 

    host myhost {
       hardware ethernet 00:01:08:00:ad:33;
       option host-name "myhost";

or if you're clever write a bit of perl to do that automatically,
