That's going to be true of any installation that involves your DHCP 
server since you typically have only one and it has to be set up 
specifically for your subnets.  For the moment at least, we run drbl in 
a lab setting using its DHCP/PXE booting only on a separate subnet that 
we use for cloning.  If we want access to the images from other networks 
we use a CD or USB boot to clonezilla and connect to the other interface 
on the server.  If I did that more often, I'd probably set up the drbl 
box to handle all dhcp or configure the main dhcp server to have the 
same booting options.
