	HN Discussion: ↓Title is clickbait since luksSuspend is a Debian-specific extension, not officially supported kernel feature •Explains the technical context of why keys remain in RAM during suspend but not hibernate ↑This regression matters because silent security bugs don't announce themselves ~Hibernating to disk is a better protection than relying on LUKS suspend key wiping ↑Recurring critical C bugs suggest systemic issues with large open source C codebases
