Remount the /dev/shm Partition in Fedora/CentOS

This is to assist with a CSF warning you may receive about /dev/shm being incorrectly mounted, simply run the following:

nano /etc/fstab

Replace this line:

tmpfs /dev/shm tmpfs defaults 0 0

With this one:

tmpfs /dev/shm tmpfs defaults,noexec,nosuid 0 0

Save & Exit nano, then remount using the following command:

mount -o remount /dev/shm
