Ensure nodev option set on /dev/shm partition

中级别 1自动化ros

说明

The nodev mount option specifies that the filesystem cannot contain special devices. The audit requires the nodev mount option on /dev/shm 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.

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /dev/shm partition. See the fstab(5) manual page for more information. Run the following command to remount /dev/shm : # mount -o remount,nodev /dev/shm
