Andreas Jaeger f80792b1ce Remove obsolete rstbash and '.. path' 
The rst2bash tool used the ".. path" syntax to update files. Since we're
not using rst2bash anymore, remove all of this.

Remove also the rst2bash documentation.

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 Ubuntu:

    # apt install chrony

    For RHEL or CentOS:

    # yum install chrony

    For SUSE:

    # zypper install chrony

  2. Configure the chrony.conf file and comment out or remove all but one server key. Change it to reference the controller node.

    For RHEL, CentOS, or SUSE, edit the /etc/chrony.conf file:

    server controller iburst

    For Ubuntu, edit the /etc/chrony/chrony.conf file:

    server controller iburst

  3. Comment out the pool 2.debian.pool.ntp.org offline iburst line.

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