1.1.8 Ensure nodev option set on /var partition


The nodev mount option specifies that the filesystem cannot contain special devices.


Since the /var filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices in /var .


Run the following command to remount /var :

# mount -o remount,nodev /var

/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.
