Hi all,
         Here is a patch to be applied to the file common/parse.c that 
enables defining new options and using them in /etc/dhclient.conf.

*** parse.c	Wed Jun 27 00:03:32 2001
--- ../../../dhcp-3.0pl1/common/parse.c	Tue Jan  7 16:36:13 2003

  	enum dhcp_token token;
  	unsigned arrayp = 0;

  	int recordp = 0;
  	int no_more_in_record = 0;
***************
*** 1033,1036 ****

+ 	     /*          or has been defined before by the client */
+ 	     known = 1;
+ 	}
+
  	/* Parse the option code. */
  	token = next_token (&val, (unsigned *)0, cfile);

+ 	     /* printf ("Code %d already is being used for %s",
+ 		option->code, dhcp_options [option->code].name ); */
+ 	     known = 1;
+ 	}
+
  	token = next_token (&val, (unsigned *)0, cfile);
  	if (token != EQUAL) {

  	}
! 	option -> universe -> options [option -> code] = option;
! 	option_hash_add (option -> universe -> hash,
! 			 (const char *)option -> name,
! 			 0, option, MDL);
  	return 1;
  }
--- 1287,1298 ----
  		   XXX may start out static. */
  	}
! 	if (!known) {
! 	     option -> universe -> options [option -> code] = option;
! 	     /* Sharad: Changing dhcp_options[i] */
! 	     memcpy (&dhcp_options[option->code], option, sizeof (option));
! 	     option_hash_add (option -> universe -> hash,
! 			      (const char *)option -> name,
! 			      0, option, MDL);
! 	}
  	return 1;
  }


Hope it helps,
Sharad
