These settings :

request domain, domain-name-servers, routers, subnet-mask, option-143;
require option-143;


  when added to the linux clients' /etc/dhclient.conf file will ensure
that only DCHPOFFERs that have the option-143 set will be accepted.
This option is pulled out of thin air and is ISC DHCPD v. 2 dependent.
ISC's DHCPD version 3 allows us to set our own named options, which
is clearly superior.
Making sure our DHCP server sets this option in its DHCPOFFER packets
is then sufficient to ensure that our DHCP settings are used when 
running Linux, again allowing our DHCP server to coexist peacefully with
the existing DHCP server.
