Following up on the previous email announcing the Foundation's intent to add S4 hibernate support to FreeBSD [1], kib@ has started working on a more detailed design document for this: https://hackmd.io/@eJNIw-SNShyq1LSp2azAcw/Bka-kXTpge There are still a couple unsolved bits of the design, so we'd like to gather some more feedback on this document. If you could reply with any feedback within a week (before Oct 23rd) that would be ideal for us! Thanks, Aymeric on behalf of the FreeBSD Foundation [1] https://lists.freebsd.org/archives/freebsd-current/2025-August/008616.html
