no and no.

it's only required that the results is reproducible, that is bit by bit identical…

my crystal ball is broken, sorry…

there surely are situations where different kernels (much like different
libraries) will cause variations in the build artifacts. many times it
will not matter and sometimes it will and we don't really have much experience
with that *yet*.

I'm inclined to file a bug report against dpkg to document the kernel 
used in the .buildinfo files and (hereby) am asking the reproducible builds team
for comments / advice on this.

And probably we should amend debian-policy for this too, but I also 
think we'd rather do this via a new bug report at some later point in time.

Thanks, Adrian, for making sure we don't forget (this pretty old aspect).
