Doug Hellmann e39304d4ae fix pdf build
The PDF build does not include content multiple times if the same file
is included in a toctree more than once. That means we need to
restructure the guide to handle the common parts differently. This
approach merges some of the previously split sections back together
using inline prose to indicate where minor variations apply for
different operating systems but retaining separate files for cases where
the differences are significant.

.. _environment-ntp-other:
=============
Other nodes
=============
Other nodes reference the controller node for clock synchronization.
Perform these steps on all other nodes.
Install and configure components
================================
1. Install the packages.
For Debian or Ubuntu:
.. code-block:: console
# apt install chrony
For Red Hat:
.. code-block:: console
# yum install chrony
.. end
For SUSE:
.. code-block:: console
# zypper install chrony
.. end
2. Edit the ``/etc/chrony/chrony.conf`` file and comment out or remove all
but one ``server`` key. Change it to reference the controller node:
.. path /etc/chrony/chrony.conf
.. code-block:: shell
server controller iburst
.. end
3. Comment out the ``pool 2.debian.pool.ntp.org offline iburst`` line.
4. Restart the NTP service.
For Debian or Ubuntu:
.. code-block:: console
# service chrony restart
.. end
For Red Hat or SUSE:
.. code-block:: console
# systemctl enable chronyd.service
# systemctl start chronyd.service
.. end
