I suggest changing the package description as follows, in part to make
it easier to differentiate from the "dhcp" package (which apparently
corresponds to version 2 of the same software):
---------------- Current:
Description: DHCP server for automatic IP address assignment
 Dynamic Host Configuration Protocol (DHCP) is a protocol like BOOTP
 (actually dhcpd includes much of the functionality of BOOTPD!). It assigns
 IP addresses to clients based on lease times. DHCP is used extensively
 by Microsoft and more recently also by Apple. It is probably essential
 in any multi-platform environment.
 .
 Multiple Ethernet Interfaces are supported by this DHCP package.
 .
 Note: This package _requires_ a 2.2.x or later Linux kernel. 2.0.x kernels
 are _not_ supported.

 This is the DHCP server from version 3 of the Internet Software
 Consortium DHCP package (http://www.isc.org). New features since
 version 2.0 include:
 .
     - DHCP Failover Protocol support
     - OMAPI, an API for accessing and modifying the DHCP server and
       client state.
     - Conditional behaviour
     - Storing arbitrary information on leases
     - Address pools with access control
     - Client classing
     - Address allocation restriction by class
     - Relay agent information option support
     - Dynamic DNS updates
     - Many bug fixes, performance enhancements, and minor new DHCP
       protocol features.
