%description
dhcp-fwd forwards DHCP messages between subnets with different sublayer
broadcast domains. It is similar to the DHCP relay agent dhcrelay of
ISC's DHCP, but has the following important features:

* Runs as non-root in a chroot-environment
* Uses AF_INET sockets which makes it possible to filter incoming
  messages with packetfilters
* The DHCP agent IDs can be defined freely
* Has a small memory footprint when using dietlibc


%description sysvinit
dhcp-fwd forwards DHCP messages between subnets with different sublayer
broadcast domains.

This package provides the scripts which can be used to start dhcp-forwarder
with the SysV initconcept.


%description upstart
dhcp-fwd forwards DHCP messages between subnets with different sublayer
broadcast domains.

This package provides the scripts which can be used to start dhcp-forwarder
with the upstart initconcept.


%description minit
dhcp-fwd forwards DHCP messages between subnets with different sublayer
broadcast domains.

This package provides the scripts which can be used to start dhcp-forwarder
with the minit initconcept.


%description systemd
dhcp-fwd forwards DHCP messages between subnets with different sublayer
broadcast domains.

This package provides the scripts which can be used to start dhcp-forwarder
with the systemd initconcept.
