From the kernel docs, `image-size` section, which relates to the hibernation image size. > Reading from it returns the current image size limit, which is set to around 2/5 of the available RAM size by default. I have successfully been hibernating a laptop after a few hours in suspend with swap allocated 50% the size of my RAM, so 8GB when I had a 16GB laptop, and 16GB now on a 32GB laptop. Never had any issues.
