Fedora reawakens the hibernation debate

I wonder how Windows does it. Also whether, upon hibernation a new key can be generated for the hibernation data, and then stored in the TPM to be used to recover on the next boot without human intervention.

OTOH, maybe this is all pointless given the increasing accessibility of cold boot attacks... after reading e.g., <https://thehackernews.com/2018/09/cold-boot-attack-encryp...> I wonder if the days of having the encryption key ever stored in RAM need to come to a close.
