Uninstall DHCP Server Package

An XCCDF Rule

Description

If the system does not need to act as a DHCP server, the dhcp package can be uninstalled. The dhcp-server package can be removed with the following command: 
$ sudo zypper remove dhcp-server

Rationale

Removing the DHCP server ensures that it cannot be easily or accidentally reactivated and disrupt network operation.
