Resolution

SOLUTION VERIFIED

This solution has been verified to work by Red Hat Customers and Support Engineers for the specified product version(s).

Remove any comments for the shebangs (i.e. #!/bin/bash) in the rc.local script, so that it starts correctly with the she-bang sequence:
Raw

#!/bin/bash

The issue was the /etc/rc.d/rc.local. This was missing from the top of the file

cat /etc/rc.d/rc.local

#!/bin/bash

# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES

#

# It is highly advisable to create own systemd services or udev rules

# to run scripts during boot instead of using this file.

#

# In contrast to previous versions due to parallel execution during boot

# this script will NOT be run after all other services.

#

# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure

# that this script will be executed during boot.
