Doug Hellmann c7bfdbb44f split install guide into separate files by OS 
Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.

Controller node

Perform these steps on the controller node.

Install and configure components

  1. Install the packages:
# zypper install chrony

  1. Edit the /etc/chrony.conf file and add, change, or remove these keys as necessary for your environment:

    server NTP_SERVER iburst

    Replace NTP_SERVER with the hostname or IP address of a suitable more accurate (lower stratum) NTP server. The configuration supports multiple server keys.

    Note

    By default, the controller node synchronizes the time via a pool of public servers. However, you can optionally configure alternative servers such as those provided by your organization.

  2. To enable other nodes to connect to the chrony daemon on the controller node, add this key to the /etc/chrony.conf file:

    allow 10.0.0.0/24

    If necessary, replace 10.0.0.0/24 with a description of your subnet.

  3. Start the NTP service and configure it to start when the system boots:

    # systemctl enable chronyd.service
# systemctl start chronyd.service
