   From the man-page:

   "The host-identifier option statement [...] identifies a DHCPv6 
client in a host statement."

   So, what you suggest seems valid only if you're running a DHCPv6 

   For classic (IPv4) DHCP, the only data items you can use to identify 
a host are
   the 'dhcp-client-identifier' option and the network hardware address.
