Seems like case in point for why we do not (and should not) support
hibernation.

If "not support" means not enabling it out of the box and/or not creating a swap partition, that's fine by me. I'd be a sad panda if you introduced roadblocks that would prevent hibernation and required heavily patching GNOME to enable it, though. As I mentioned in the other thread, suspend to RAM doesn't work for me, so I rely on hibernation pretty heavily. I found one of the mentioned roadblocks some time ago, when I wanted to enable hybrid sleep on one of my other machines. It can be easily configured through logind, but gnome-settings-daemon overrides the power button event and only offers a limited selection of actions (hybrid sleep not being one of them). It also doesn't offer "don't consume the event, ignore it" action. So even though I can easily trigger hybrid sleep from command line, I can't trigger it when pressing the power button or perhaps closing the lid. That's fine for me (although inconvenient), but not fine for my parents. Of course I reported this against gsd, but nothing happened. So when you make changes, just please think about people who might want to enable hibernation or some other action for some reason, and don't completely lock them out (add a gsettings option or something). Thanks.
