- IF - a separate partition exists for /dev/shm. Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /dev/shm partition. See the fstab(5) manual page for more information. Example: tmpfs /dev/shm tmpfs defaults,rw,nosuid,nodev,noexec,relatime 0 0 Run the following command to remount /dev/shm with the configured options: # mount -o remount /dev/shm Note: It is recommended to use tmpfs as the device/filesystem type as /dev/shm is used as shared memory space by applications.
