4.1.2 Syslog Error: Failed to insert module 'ip_tables': Operation not permitted

During an Oracle Linux 8 installation, the following message is observed in /var/log/messages:systemd log:

1]: Failed to insert module 'ip_tables': Operation not permitted

This error can be safely ignored, as the ip_tables kernel module subsequently loads successfully, as shown in the output of the following command:

# grep IPTABLES /boot/config*
CONFIG_IP_NF_IPTABLES=m
CONFIG_IP6_NF_IPTABLES=m
#
