Verify that a separate file system has been created for "/var/tmp".

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

$ sudo grep /var/tmp /etc/fstab

/dev/mapper/... /var/tmp xfs defaults,nodev,noexec,nosuid 0 0

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