+==== Speed-up hibernation ====
+When hibernating the system (storing the state on disk), all RAM content is dumped into the swap area. This includes also caches and other rubbish which can be safely dropped.
+By default, the pm-utils try to fit the state under 2/5 of the RAM size when hibernating to shorten the store/reload time. This is however not a hard-limit, if the content cant fit, then more data is stored. To change the limit, one can edit /sys/power/image_size to desired soft-limit in bytes. In particular, 0 means that the system will hibernate with the smallest amount of data and all caches will be dropped.
