I'm just looking for the best way to avoid Fedora laptop users unexpectedly losing their data. I spent some time reading through the kernel docs on this last night, as ultimately that's what we rely on. <a href="https://www.kernel.org/doc/Documentation/power/">https://www.kernel.org/doc/Documentation/power/</a> Regardless of how the hibernate generator might potentially be changed to attempt to locate a valid swap partition with hibernate data, or how difficult that may be given the nature of running in an initrd and as a generator, we still need to follow the kernel requirements for suspend-to-disk. The documented way there is resume= so I feel that's the best way to direct the Fedora bug as it stands. If the anaconda guys disagree then I think the best course of action to avoid unexpected data loss is to have upower not default to HybridSleep but go straight to shutdown. I'll update the bug comments later today with the results of this thread. Thank you all for your input.
