InformationThe nodev mount option specifies that the filesystem cannot contain special devices. 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.
SolutionEdit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /run/shm partition. See the fstab(5) manual page for more information. Run the following command to remount /run/shm: # mount -o remount,nodev /run/shm
