Title

RHEL 8 must use a separate file system for /var/tmp. (Cat II impact)

Discussion

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

Check Content

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.

Fix Text

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