Disabling Swap During Installation
Do not specify a swap device.
Disabling Swap at Runtime
swapoff -a
The command disables swapping on the specified device (or on all devices if -a is specified) in kernel.
Note that the command does not modify /etc/fstab so if there are swap devices mentioned there, swap will be re-enabled upon reboot. In order to prevent the kernel to re-enable swapping, remove the swap devices from /etc/fstab.
