Fedora reawakens the hibernation debate

Absolutely. Save and restore is a good thing all round. Posix systems can't do what Android Apps do by default, but there's no reason why they can't individually support session restore, and indicate to the DE that they do. If enough do then it would be feasible for the OS/DE to respond to system memory pressure by closing such opted-in applications which are not showing. I would love to see progress here. Even teach bash to restore itself and the processes its running (a hard task in general no doubt). It's all a great insurance against system crashes of various sorts; I can't imagine using a text editor which doesn't keep recovery information.

I just don't think it's a replacement for system suspend. When I hit the power button and put my Android phone in my pocket, it's not actually closing apps never mind powering down the system, it's just putting them in a lower power state until I switch the screen back on.
