Well, within sarge: If I understood it right, an ABI-changes on security
doesn't hurt the installer till the kernel is pushed into sarge proper.
So, pushing the kernel only if we do a point release (and perhaps even
keeping the old kernel source and images in if that's possible, so that
even business card is not broken).
Of course, this is still a can of worms - rebuilding all kernels,
rebuilding all modules, rebuilding the installer, but at least we know
what to do.
(And so to the initial question: It handles both. I would try to handle
any further kernel change exactly the way we do after release, with one
extra slot for ABI-transitions at release, and start to consider the
kernel as hard frozen as soon as possible.)
Cheers,
Andi
