#273253 — Hibernate works with secure boot on OpenSUSE

Message-ID<JqggV-exEw-5@gated-at.bofh.it>
Apparently hibernate works on OpenSuse with secure boot enabled when swap is within an encrypted drive or encrypted itself.

Is that true? If it is then why hasn't Debian followed suit?

Seems to be true.

https://unix.stackexchange.com/questions/591488/why-does-the-kernel-lockdown-prevent-hibernation
seems to indicate it's a feature Suse developed. I have no idea if
that's in the mainstream kernel by now but I guess not. If it's
integrated, it'll get into Debian too at some point. If no, then it
would need some dev to take an interest and integrate and test and
maintain.
