Hi again!

Following up on the previous email announcing the Foundation's intent t= o add S4
hibernate support to FreeBSD [1], kib@ has started working on a more detail= ed
design document for this:

There are still a couple unsolved bits of the design, so we'd like to g= ather
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!

I've gone ahead and provided my feedback, and aske= d my questions in the doc.

It looks good, but ther= e's a few booting issues that bit me recently when I did LinuxBoot that= I think are relevant, so I've flagged them there.
