Hibernate in Fedora 18

As there is no direct link to Hibernate in current state of Fedora 18, here is a way to easily create a script that will hibernate the system:

sudo /bin/sh -c 'echo disk > /sys/power/state'

As if that is not enough, there is an even easier way:

pm-hibernate

This utility is a part of pm-utils package.
