The nodev mount option specifies that the filesystem cannot contain special devices.
Rationale:
Since the user partitions are not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices.
Fix:
Run the following command to remount /home:
# mount -o remount,nodev /home
Also the content shown by following command should present in /etc/fstab appropriately:
# echo "$(grep /dev/shm /etc/mtab)"
Parameter:
[yes/no]
Technical Mechanism:
Run the following command to remount /home:
# mount -o remount,nodev /home
