Fix Recommendation

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

Check Contents

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

$ mount | grep /var/tmp

/dev/mapper/rhel-tmp on /var/tmp type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k)
Note: Options displayed for mount may differ.

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