Verify that a separate file system/partition has been created for "/var/tmp".
Check that a file system/partition has been created for "/var/tmp" with the following command:
$ sudo grep /var/tmp /etc/fstab
UUID=c274f65f /var/tmp xfs noatime,nobarrier 1 2
If a separate entry for "/var/tmp" is not in use, this is a finding.
