The output that these macros create is really weird because it contains the instructions three times. It isn't really reader friendly. Instead, I'd prefer having here a custom text that contains just a single grep command that will find all 3 audit rules.

ocil_clause: 'fewer than two remote NTP servers are configured for the NTP daemon in use'

ocil: |-
Verify that {{{ full_name }}} is configured with more than one remote NTP server.

If the system uses <tt>chronyd</tt> as the NTP daemon (the default), run the following command:
<pre>$ sudo grep -E "^[[:space:]]*server[[:space:]]+" {{{ chrony_conf_path }}}</pre>

Also check any drop-in configuration files the daemon includes.

If the system uses <tt>ntpd</tt> as the NTP daemon, run the following command instead:
<pre>$ sudo grep -E "^[[:space:]]*server[[:space:]]+" /etc/ntp.conf</pre>

Two or more <tt>server</tt> lines must be returned for the NTP daemon that is in use.

ocil: |-
Verify that prelinking is disabled on {{{ full_name }}}.

First determine whether the <tt>prelink</tt> package is installed:
<pre>$ rpm -q prelink</pre>

If the package is not installed, prelinking cannot be in use and the requirement is met.

If the package is installed, verify that prelinking is disabled:
<pre>$ grep -i PRELINKING /etc/sysconfig/prelink</pre>

The output must be:
<pre>PRELINKING=no</pre>
