Replying to myself for the first point:
> Can you think of a way to do handle just exactly +1 version upgrade (9.7p1 -> 9.8p1) more smoothly

I looked a bit more and rather than just the path change the problem
would be this protocol change:
        /*
         * Protocol from reexec master to child:
         *      string  configuration
+        *      uint64  timing_secret
+        *      string  host_keys[] {
+        *              string private_key
+        *              string public_key
+        *              string certificate
+        *      }
         *      string  included_files[] {
         *              string  selector
         *              string  filename

so I don't see any remotely clean way of doing that for this particular
update.

Unless there's a great idea somewhere, let's focus this bz about
further updates -- it doesn't make sense to freeze this protocol in my
opinion but perhaps add a version field first the next time there's a
breakage, so at least n->n+1 might be handled.

Thanks
