Details
The nodev mount option specifies that the /run/shm (temporary filesystem stored in
memory) cannot contain block or character special devices.
*Rationale*
Since the /run/shm filesystem is not intended to support devices, set this option to ensure
that users cannot attempt to create special devices in /run/shm partitions.
Solution
Edit the /etc/fstab file and add nodev to the fourth field (mounting options of entries that
have mount points that contain /run/shm. See the fstab(5) manual page for more
information.# mount -o remount,nodev /run/shm
