Check Text (C-230295r1017106_chk)
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 (F-32939r567632_fix)
Migrate the "/tmp" directory onto a separate file system/partition.
