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

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

# systemctl is-enabled tmp.mount
enabled

If the "tmp.mount" service is not enabled, check to see if "/tmp" is defined in the fstab with a device and mount point:

# grep -i /tmp /etc/fstab
UUID=a411dc99-f2a1-4c87-9e05-184977be8539 /tmp ext4 rw,relatime,discard,data=ordered,nosuid,noexec, 0 0

If "tmp.mount" service is not enabled or the "/tmp" directory is not defined in the fstab with a device and mount point, this is a finding.
Fix Text (F-36247r602444_fix)
Start the "tmp.mount" service with the following command:

# systemctl enable tmp.mount

OR

Edit the "/etc/fstab" file and ensure the "/tmp" directory is defined in the fstab with a device and mount point.
