1.1.2 Set nodev option for /tmp Partition

Information

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

Rationale:

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

Solution

Edit the /etc/fstab file and add nodev to the fourth field (mounting options). See the fstab(5) manual page for more information.

# mount -o remount,nodev /tmp

Default Value:

OS Default: N/A
