Ensure nosuid option set on /tmp partition

中级别 1自动化ros

说明

The nosuid mount option specifies that the filesystem cannot contain setuid files. The audit requires the nosuid mount option on /tmp when it is a separate mount (findmnt); not applicable otherwise. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
