In dhcp.c is this code snippet:

|     case DHCLIENT:
|       /* First, set up dhclient.conf */
|
|       if ((dc = file_open(DHCLIENT_CONF, "w")))
|       {
|         fprintf(dc, "send dhcp-class-identifier \"d-i\";\n" );
|         if (dhostname)
|         {
|           fprintf(dc, "send host-name \"%s\";\n", dhostname);
|         }
|         fclose(dc);
|       }

So only when dhostname is set, it sends the hostname in the request.

I hope the above text did help.

Beside sending the hostname for cable providers,
there is also the need to send dhcp-class-identifier "d-i",
to allow DHCP preseeding.
