Dear Richard, thank you very much for all your feedbacks. I can see that you forsee many problems in doing that (even as root) and in just one program as part of system utility. I am sorry but if you can highlight few problems here it will be helpful for me(and others) to understand. Also I wanted to understand, why it is meant only for Hibernation? Thank you so much !
