title: 'Uninstall DHCP Server Package'

description: |-
    If the system does not need to act as a DHCP server,
    the dhcp package can be uninstalled.
    {{% if 'ubuntu' in product %}}
    {{{ describe_package_remove(package="isc-dhcp-server") }}}
    {{% elif product in ['ol8', 'ol9', 'rhel8', 'rhel9', 'sle12', 'sle15'] %}}
    {{{ describe_package_remove(package="dhcp-server") }}}
    {{% else %}}
    {{{ describe_package_remove(package="dhcp") }}}
    {{% endif %}}

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