OL 8 must use a separate file system for "/var".

The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.

Verify that a separate file system has been created for "/var" with the following command:

     $ sudo grep /var /etc/fstab 

     /dev/mapper/...   /var   xfs   defaults,nodev 0 0

If a separate entry for "/var" is not in use, this is a finding.

Migrate the "/var" path onto a separate file system.
