InformationThe nodev mount option specifies that the filesystem cannot contain special devices.
Since the /dev/shm filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create special devices in /dev/shm partitions.
SolutionRun the following command to remount /dev/shm :
# mount -o remount,nodev /dev/shm
/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.
