The '.config' files in '/etc/init/' are overwritten on update of 'initscripts' package

Issue

After upgrading to Red Hat Enterprise Linux 6.2 from 6.1, it was noticed that the custom changes that had been made to '/etc/init/control-alt-delete.conf', to prevent the reboot of the system by a key-press of 'ctrl-alt-del', were overwritten due to the 'initscripts' package being updated.

The Unix STIG, which is mandatory guidance for all DoD systems, requires that the 'ctrl-alt-del' reboot sequence be disabled for all systems not in a controlled access area. Prior to Red Hat Enterprise Linux 6, this functionality was disabled in '/etc/inittab'. With the change from 'SysVinit' to 'upstart' in Red Hat Enterprise Linux 6, it is now in '/etc/init/control-alt-delete.conf'.

The overwriting of the file on an update of the 'initscripts' package, means that the custom changes to this file must be re-deployed to each Red Hat Enterprise Linux 6 system, after every update to the 'initscripts' package.
