InformationThe nodev mount option specifies that the filesystem cannot contain special devices.
Since the /tmp filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices in /tmp .
SolutionRun the following command to remount /tmp :
# mount -o remount,nodev /tmp
/etc is stateless on Container-Optimized OS. Therefore, /etc cannot be used to make these changes persistent across reboots. The steps mentioned above needs to be performed after every boot.
