No, you set them in the system object.  This can be found under
Networking in the web console, or by running "cobbler system edit
--name=<system name> --dhcp_tag=<arbitrary value>".

If you do a search for "dhcp_tag" in the cobbler list archives, you
should find a thread on how we use it to manage replicated cobbler
instances on different subnets.
