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/partition has been created for non-privileged local interactive user home directories.

$ sudo grep /tmp /etc/fstab

/dev/mapper/rhel-tmp  /tmp  xfs   defaults,nodev,nosuid,noexec 0 0 

If a separate entry for the file system/partition "/tmp" does not exist, this is a finding.

Fix Text

Migrate the "/tmp" directory onto a separate file system/partition.
