PXE Client configuration

Greetings,

	We're running dhcp 3.0.5, RHEL packages, and readying ourselves to
deploy a configuration that will allow PXE booting.  We have this
working successfully in the lab, but we're looking to restrict this on
some subnets.  So, the question is, how?

	I have this class definition, but it matches on every subnet.  I know I
can add a deny members of "pxeclients" to each subnet, but there are far
more subnets I want to deny than subnets to allow.  Is there a way to
deny by default and allow only where explicitly defined?

class "pxeclients" {
   match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
   next-server pxe.example.com;
   filename "x86pc/undi/wpemenu/startrom.0";
}

Thanks,
